In @packages/engine/ui/node_model.h:
- Around line 951-953: Widen Node’s previous_box_shadow_extent from int16_t to
int32_t, and update the layout_snapshot.cpp assignment to store
boxShadowExtent() without clamping or narrowing so previous-bound invalidation
retains the full extent.
In @packages/engine/ui/render.cpp:
- Around line 7184-7209: Update rerecordNodeCommands and the root-scroll
translation path to reject retained-list updates whenever multicolumn content
has been recorded, forcing a full record so columnCopies ranges and commands are
rebuilt. Use replicateColumns as the identifying point for detecting multicolumn
content.
- Around line 2124-2134: Update ShapedClips::entries() and ShapedClips::saved()
to select separate static storage for each render core using
gea_current_render_core(), so concurrent replay paths do not mutate shared
vectors. Leave the simple replay path and unrelated clipping behavior unchanged.
In @packages/engine/ui/style.cpp:
- Around line 18004-18012: Update StyleSheet::recomputeSiblingsFrom to skip
nodes identified by isGeneratedPseudoNode while traversing the sibling chain,
and continue recomputing styles for all other siblings.
- Around line 6892-6896: Update lineClampWrites so both the `none` branch and
the regular shorthand result also write `Property::LineClampDiscard` as zero and
report five writes. Adjust its output capacity accordingly, and add
`Property::LineClampDiscard` to the `line-clamp` and `-webkit-line-clamp`
removal list in removeInlineStyleProperty.
In @packages/engine/ui/text.cpp:
- Around line 1637-1638: Update the bitmap emphasis-mark path to use the same
horizontal origin as the glyphs: compute and reuse the aligned `lineX` based on
`line.width - hanging - trimmedIndent`. Pass that origin to `drawEmphasisMarks`
instead of recalculating alignment from the full `line.width`.
In @packages/engine/ui/tree_nodes.cpp:
- Around line 629-634: Update Tree::removeNode to delegate to an internal helper
that accepts a restyle-siblings flag. Pass false when recursively removing
children and skip recomputeSiblingsFrom for those calls; preserve sibling
restyling for the top-level removal.
In @packages/engine/ui/tree_render.cpp:
- Around line 286-287: Update dirtyRectWithRasterGuard to include box-shadow
paint extent in its padding, using the larger of the current extent from
boxShadowExtent and node.render.previous_box_shadow_extent. Combine that extent
with the current border-image outset using the larger value so the dirty
rectangle covers both effects.
In @packages/engine/ui/tree_style.cpp:
- Around line 599-600: Stop zeroing the stored border width when `border-style:
none` is applied in the style update paths. Update `computedBorderWidth` to
return zero when the side’s `border_relief` has `kBorderStyleNone`, while
preserving the stored width so a later relief-only change to `solid` restores
it.
In @packages/engine/ui/view.cpp:
- Around line 2757-2760: Update the untransformed clipping block in the function
containing this diff to call saturateRect16 with x, y, w, and h, replacing the

Widen the stored box-shadow extent.
layout_snapshot.cpp clamps boxShadowExtent() to 32767. When the actual extent is larger, previous-bound invalidation uses the smaller stored value. Old shadow pixels outside that range can remain uncleared.

Preserve the border width when border-style is none.
The declaration-order failure does not occur because setComputedBorderWidth also applies the none rule after width updates. However, a relief-only update from none to solid can leave the width at zero because the relief setter does not restore the previous width. Store the width and apply the none rule only when reading the computed width.

An absolutely positioned box shares no baseline, so `baseline` and
`last baseline` use their fallback edge. The static-position path resolved
that edge in the box's own direction/writing mode; Chrome, Firefox and
Safari resolve it to the grid's start/end. In-flow grid items keep the
self-start/self-end fallback.
The native baseline regression pinned the old child-relative edge for an
LTR child in an RTL or vertical-rl grid; it now expects the grid's end.

Top/right/bottom/left are stored as int16 with kUnset (-32768) meaning auto. Resolved lengths saturate at int32, and storing them truncated the low 16 bits: -65536px and -99999999999px became 0, 99999999999px became -1 and -40000px became 25536, so "hidden far off-screen" content painted at the page edge. Both offset sinks (class/selector rules and inline style) now keep kUnset and clamp every other length to [-32767, 32767]. A resolved length of exactly -32768px still reads as auto, as before.

Baseline alignment needs baselines that cross the cross axis. When a flex
item's inline axis runs along the cross axis instead (a column, or a row
of a vertical container), CSS Align uses the fallback alignment: safe
self-start/self-end in the item's own writing mode, which wrap-reverse
does not flip. Gea still ran baseline alignment there, so a lone item
stayed at the flex-relative cross start and wrap-reverse moved it to the
wrong edge.
Such items now resolve through baselineFallbackAlignment, stay out of the
line's shared baseline, and skip the wrap-reverse baseline mirror. Only
real flex containers are affected; inline formatting rows are unchanged.
Chrome and Safari pass both tests; Firefox does not.

When an absolutely positioned box takes its static position from inline layout, its static-position rectangle spans the line box's block extent (CSS Position 3, 4.1), and align-self aligns the box within it. Gea kept only the line's top edge, so the box stuck to the top of the line for every align-self value. Inline layout now records the line box height with the static position (0 for a line that is not laid out yet), and alignedAbsoluteOffset applies an explicit align-self along the block axis of horizontal-tb containers. align-self: auto keeps the previous start placement.

ViewRenderer::recordBox accepts boxes outside the tree, for which ViewGeometry::nodeIndex returns -1. backgroundPlacement still read treeState().nodes[nodeId] for local attachments and non-border-box origins, i.e. nodes[-1]. The css-3d-cube native test paints such a box; depending on memory layout the out-of-bounds read raised SIGBUS (KERN_PROTECTION_FAILURE in backgroundPlacement, via recordBackgroundGrid). Detached boxes now skip the scroll and edge adjustments. Evidence: run-gea-css-3d-cube-pipeline.sh no longer crashes (5/5 runs); it still reports the same positive-z assertion as e6115c3. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
A background-attachment: local layer scrolls with a scroll container's contents, so its painting area is the scrollport: border-box clipping behaves as padding-box, while content-box is unchanged (upstream attachment-local-clipping-color-1/2/3). backgroundClip now resolves that for hidden/auto/scroll overflow, so color and image layers, and the opaque-border fast path, all see the padding box. Before, a translucent border of such a box blended over its own background. With the next commit this passes css/css-backgrounds/background-attachment-local-hidden.html (Chrome and Firefox pass it; Safari does not). Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
The non-antialiased Canvas::strokeRoundedRect drew four edge rectangles and four corner arcs that overlapped where they met, and the arcs included the pixel on the inner radius. Translucent borders therefore blended twice at the joins: a square 10px rgba border had dark corner squares, a rounded one had dark seams, and the ring bulged 1px into the padding area at each tangent point. Each row is now painted once as the outer shape's span minus the inner (padding-edge) shape's span, using fillRoundedRect's scanline, so the ring is the exact complement of a fill of the inner box. Opaque borders only change along the inner curves (about 25 pixels per corner for a 34px radius and 10px width), where the ring now keeps its width. The antialiased and percent-radius paths are unchanged.

The keyword was rejected, so the declaration was dropped and the color filled the whole border box. Clip value 4 now paints the color along the border's own geometry: the same stroke for a uniform width (radii included), the side rectangles otherwise. Gradient layers still ignore background-clip, as they already did for padding-box and content-box. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
text-align-last is a new inherited style field, stored in ComputedStyle padding so the struct keeps its size. A DrawText command now carries it: the drawer applies it to lines a forced break ends and, when LayoutEngine::endsFormattingLine says the run closes its paragraph (a <br>, a block box or the container end follows), to the run's final line. Aligning a line also stops counting the collapsible spaces that hang at its end and the leading space the inline flow trims from line 0. Both put right- and center-aligned text a space off before. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Outer layers were dropped at parse time, so only inset shadows ever painted. A value's first inset layer still wins; otherwise its first outer layer is kept (var() values now parse at runtime instead of compiling outer-only shadows to none). recordOuterBoxShadow grows the border box by the spread with the CSS Backgrounds outset-adjusted radii (a circle stays a circle), offsets it, and approximates the Gaussian blur with constant-alpha bands. Nothing paints inside the border box: over an opaque border-box background each band is one native rounded fill or ring and fully covered parts are skipped; otherwise rows are painted as spans with the box knocked out. Node bounds grow by the shadow's reach, and the reach at the last snapshot is kept in RenderState padding, so dirty regions cover both the new and the old shadow.

A gradient whose stops share one opaque colour, such as the common linear-gradient(c, c) image layer, went through the dithered gradient rasterizer. On RGB565 that speckled a colour a plain fill paints flat (#008000 alternated between two greens), so the same colour differed between background-color and background-image. Such gradients now fill directly, which is also cheaper. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
line-clamp and its longhands were not parsed. A block container with continue: collapse now walks its content after layout: past its max-lines'th line, or without max-lines past the last content that fits its used height, every box is hidden from painting and hit testing, a text run the clamp point cuts paints only its first lines, and an automatic height ends at the clamp point. Lines inside inline wrappers and plain blocks count; independent formatting contexts are units. As in CSS Overflow 4, inline boxes, flex and grid containers, and multicol containers never clamp, so columns / column-count / column-width are tracked for that alone. -webkit-line-clamp is the legacy form, which only clamps display: -webkit-box, so it never collapses here. block-ellipsis is parsed but not painted yet. The new style fields and layout flags sit in existing padding: RareStyle, LayoutBox and ComputedStyle keep their sizes. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
vertical-align was not parsed, so every inline item sat on the baseline. One-line inline items now shift for middle, text-top, text-bottom, sub and super, and top/bottom items align to the line box edges. As in CSS, non-replaced inline boxes align by their line-height box, which differs from Gea's layout box when the line-height is below the font size, and a line holding aligned items is sized from the block's strut and every item's reach, negative ones included. The strut is only applied to lines with aligned items for now: applying it everywhere is correct CSS but would lengthen lines of small inline text that current layouts rely on. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
sticky parsed as static. It is now its own position value: the box stays in flow and, while absolute coordinates are resolved, shifts just enough to stay inset by its top/right/bottom/left from the nearest scrollport (a scroll container's padding box, or the viewport) without leaving its containing block. Sticky boxes contain absolute descendants. The offset depends on scroll positions, so while any sticky box exists the root scroll-only refresh stands down instead of dragging it along with the content; the regular path re-resolves coordinates. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
A float inside an inline wrapper now joins the enclosing block's float context, the way blocks inside inlines already do, instead of being confined to the wrapper's box. Floats end inline runs in this layout, so a float anchored where the line cannot break (inside a word or nowrap text) split the line. Move such a float to the next soft wrap opportunity, which places it after the line holding its anchor as CSS does. Line breaking now honours soft wrap opportunities between items: an overflowing item only starts a new line where the line may break, and items glued together start the next line as one unit. Collapsible spaces of atomic text collapse across items, are removed at the start of a line, and hang at its end instead of opening another line. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
block-ellipsis was parsed but never painted. A custom string from line-clamp or block-ellipsis is now interned as a CSS atom in RareStyle padding; an empty string paints nothing, like none. The clamp walk marks the text run whose line immediately precedes the clamp point; a block in between takes the ellipsis away, as in CSS Overflow 4. Phantom content (collapsible spaces, empty inline boxes) neither counts as a line nor introduces a clamp point. DrawText carries the ellipsis and the room up to the end of the line box. The painter drops trailing characters until the ellipsis fits, removes the spaces before it and appends it. The default ellipsis is U+2026 when the font has it and "..." otherwise. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
A uniform border on a rotated or scaled box was not painted at all unless the box was a full ellipse. FillTransformedRoundedRect gains a ring mode: the rasterizer paints inside the border box and outside the padding box, whose CSS inner radii it derives from the border widths. Overflow clips now carry their shape: the padding box with its inner radii, and for a transformed box the screen parallelogram, which is also clipped now (perspective projections stay unclipped as before). Display clips are rectangles, so replay saves the pixels the shape's bounds may expose (only the four corner boxes of an untransformed box), lets the clipped content paint, and restores every pixel outside the shape, blending partly covered edges. The stream replay and the node-range dirty-region replays both do this, and record-time culling uses the same clip bounds. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
The text-clip mask painted the background with glyph coverage and the text then painted over it with the same coverage, so the background bled through every partly covered edge pixel. Glyphs with no opacity between them and the clip owner paint over that background completely; leaving them out of the mask removes the fringe and matches CSS, where no part of such a background shows. Transparent and translucent text keep showing the background as before. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
columns, column-count and column-width now keep their values instead of only whether they are set, and column-fill, column-span and continue: discard are parsed; the fields sit in RareStyle padding. A multicol container lays its content out as one column (the flow thread) of the used column width (CSS Multi-column 3.4). Its column height is the definite height under column-fill: auto, else the shortest height that balances the flow over the columns without a column boundary cutting a line box or an image. column-gap separates column boxes only; it no longer spaces the content's lines. Painting records the flow thread once and copies it into every further column box, translated along the inline direction (from the right edge in rtl) and up by the column heights, each copy clipped to its column's band. The first band stays open above and the last below, so ink crossing fragmentation edges shows, which is box-decoration-break: slice. continue: discard drops overflow columns. A multicol container paints its whole subtree so the copies cover it, and text-clipped backgrounds in a copy take their glyph mask from the same copy. Node range dirty-region replays cannot follow the copies, so they are off while a multicol container exists. A container with a column-span: all child keeps a single column, since column sets are not implemented. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
border-style and border-top/right/bottom/left-style were not parsed at all, so border: 15px aqua; border-style: none solid painted all four sides. They now write each side's relief (groove, ridge, inset, outset now work outside the border shorthand too); dashed, dotted and double paint solid. none and hidden set a bit in the side's relief byte: the side's width drops to zero and the width setter keeps it there, so the order of border-style and border-width declarations does not matter. The border shorthand resets the styles before it writes the widths, so a side that was none takes the new width. Painters mask the bit out of the relief.

Logical properties were ignored. Single-side longhands (inline-size, block-size and their min-/max- forms, margin-, padding-, inset- and border- inline/block start/end including -width/-color/-style, and the logical corner radii) now classify as their physical counterparts, so the rest of the style system applies them unchanged. The two-sided shorthands (margin-/padding-/inset-inline and -block with one or two values, border-inline/-block and their -width/-color/-style forms) are applied as their two physical sides. The mapping assumes horizontal-tb and ltr; rtl and vertical writing modes still map to the same physical sides. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
text-align was applied only by the text drawer, inside each run's own box, so a line such as "Hello <span>world</span>" never moved: it stayed start-aligned, every run aligned inside its own box instead (which lost the space before the span and could overlap runs under right alignment), and direction: rtl did not move start to the right. A line made of single-line items now shifts as a whole, its trailing collapsible space hanging, together with its inline static positions and ::first-line fragments; runs on it draw start-aligned in their boxes (RenderState::inline_baseline bit 1). A text run that owns its line is still aligned by the drawer. text-align now keeps start, left, end and right apart, and LayoutEngine::physicalTextAlign resolves start and end by direction everywhere text alignment is read. Lines where a wrapping run shares its first or last line with other items keep the old alignment. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
An inline with a forced break and no visible box was laid out as one atomic box, so its later lines started at its own left edge instead of the block's. Such an inline now opens into its block's lines like one holding a block or a float, and out-of-flow children no longer prevent that. A positioned inline split across lines is the containing block of its out-of-flow children: the rect from its first fragment's inline-start and block-start edges to its last fragment's inline-end and block-end edges (CSS Position 3), the start edge on the right in rtl. After its block's layout the inline takes that rect as its box, its in-flow content keeps its place, and its out-of-flow children are positioned against it. Text fragments are measured again, since a run that owns its line gets a line-wide box for text-align. A wrapping run's leading collapsible space now also collapses into one that ends the item before it, as nowrap runs already did. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
text-emphasis and its longhands were not parsed. text-emphasis-style, -color and -position now inherit through ComputedStyle padding (a style byte and a colour), and the text drawer paints one mark per character that is neither a space nor punctuation, over or under the glyph box: filled or open dot, circle, double circle, triangle or sesame, scaled with the font. The same geometry feeds the background-clip: text mask, and the row-clipped mask pass now reaches marks outside a line's glyph box. Text commands grow their bounds to include the marks. Marks are vector shapes rather than glyphs, and lines do not grow to make room for them; string marks are unsupported. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Parse background-blend-mode as an interned per-layer list and carry each gradient layer's mode on its display command. A non-normal linear or radial gradient blends pixel by pixel with the canvas using the Compositing 1 separable and non-separable formulas. Layers blend as an isolated group, so a layer with nothing of the element painted under it keeps normal. background-clip: text used to mask every layer separately, so partly covered edge pixels picked up the lower layers twice. Those pixels now take each layer's change over the unmasked composite of the layers below it, clipping the whole background to the text once. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Parse border-image and its five longhands into one-byte interned handles in RareStyle padding. A compiled rule can now write five properties, the shorthand's reset of all longhands; such groups skip the style apply cache. A linear-gradient source is sized to the border image area (border box plus outset) and cut by the slices into nine parts drawn over the border image widths, with stretch, repeat, round and space along the edges and the middle part only with fill. Each part is a gradient box scaled so its slice lands on the tile, clipped to the tile. A painted border image replaces the border styles, and the node's dirty rect grows by the outset. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
A span with a border, padding or background that contains an in-flow block now lays the inline runs between its blocks out as fragments, each shrink-wrapped like the unsplit span and open on its split sides. The first fragment carries the inline-start edge, the last the inline-end edge, and every fragment its block edges; the blocks sit on the parent's content box. The fragments are kept in NodeRareData and painted instead of the single box. Only spans Gea places on their own line are split. In the same mixed inline and block path, a block narrower than the line now hugs the right edge in right-to-left flow. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
flex-grow floored each item's share and gave the leftover pixels to the last item, so 3:1 of 70px was 52/18. Rounding the running share instead puts every item edge on the pixel nearest its exact position: 53/17, and 33/34/33 for three equal items in 100px. Block flow now also carries the fractional part of plain percentage heights, so each such box ends on the pixel nearest its exact bottom edge: 75% and 25% of 70px are 53 and 17 instead of 53 and 18. A resized box's scroll content height follows, so its container no longer reports a phantom 1px overflow. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
display: flow-root now keeps a flag next to the block display kind, and a block container with a non-normal align-content becomes a BFC root as CSS Align 3 requires. Both contain floats and child margins and avoid outer floats. An automatic-width BFC beside floats now tries the widest layout opportunity at each position first and only narrows as its height meets more floats. Before, a box whose height follows its width (aspect-ratio) could flip between two widths forever. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Both calc() parsers split at the first operator in the order / * + -, so calc(4lh + 2 * 5px) became (4lh + 2) * 5px and calc(128px + 2 * 5px) was rejected. They now split sums at their last top-level + or -, then products at their last * or /, accept the number on either side of *, and unwrap parenthesised groups. A + or - after an operator, an opening parenthesis or an exponent stays part of the number. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
A line-clamp container now establishes a BFC, as the CSS Overflow 4 references expect. Its clamp walk treats flow-root and other BFC roots as single units, hides a block whose first content already follows the clamp point together with its background and borders, and counts kept blocks, including empty ones, so their ancestors stay visible. A block hidden that way no longer takes the ellipsis from the line before it. With line-clamp: auto a break point fits only if the boxes around it still fit once clamped: their bottom border and padding, min-height and collapsing bottom margins now count, and the clamped height includes them. An empty cleared block's collapsed margin sits above its border edge, as CSS 2.2 8.3.1 places it. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
inline-flex and inline-grid were plain flex and grid containers, so they filled the line and stood on their own. They now carry an inline flag next to the box kind and sit on the line like an image: their automatic width is fit-content, measured the way floats are, and their own aspect-ratio applies. Floated and absolutely positioned ones are blockified. blockLevelView() now answers whether a view is block-level in one place. The static style compilers emit the same display values as the engine (inline-flex 67, inline-grid 66, flow-root 32), so a declaration means the same whether it is resolved at build time or at runtime. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
An explicit align-self now centers or ends an absolutely positioned box on its block-level static position, a rectangle with no block size, and an explicit justify-self aligns it in the parent's content box, as CSS Align 3 describes. auto stays normal for such a box, so the parent's justify-items still does not move it. anchor-center behaves as center, since Gea has no anchor boxes. An inline-level absolute box that no line box placed, such as a span after a block and a float, now starts where its hypothetical line would, below the preceding block, instead of at the parent's top edge. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
display: inline made any element a block, even a span. It now makes it an inline box like a span, whatever the tag, and inline-block becomes an atomic inline-level BFC (inline plus flow-root): fit-content wide, on the line like inline-flex, painted as one group like a float (CSS 2.2 Appendix E) so its block children stay above its background. An inline-block takes its last line box's baseline. Blocks and inline boxes are searched for it in turn, collapsible white space and blocks without line boxes add none, and a clipping block stands for its bottom margin edge; without a line box, or when it clips its own overflow, it uses its bottom margin edge (CSS 2.2 10.8.1). Absolute children of an inline-block get block static positions, as in any block container. The static style compilers emit the same values (inline 64, inline-block 96). Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
CSS Align 3 / Position 3: an absolutely positioned box with both insets of an axis set and an explicit align-self/justify-self is aligned within the inset-modified containing block instead of taking the start inset. Static-position alignment now covers vertical writing modes (align-self in the block axis, justify-self in the inline axis, reversed block axis starting at the far edge), and justify-self aligns around the zero-width inline static position. A block-level absolute box after content inside an inline box starts on the next line, as the block it would be. Absolute children of inline boxes split across lines now get line-based static positions, and the node that recorded the position is kept so a relatively positioned span subtracts its own offset. Centering rounds half pixels up. WPT: align-self-static-position-001 and -002 pass (537 pass / 54 fail). Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
CSS Align 3: align-content center or end on a block container whose content box is taller than its content moves the in-flow content down; with no in-flow content, the static positions of its absolute children move instead. Applied to horizontal-tb display:block containers with a definite height or min-height that are not scroll containers, inline boxes or multicol containers. The shift is recomputed from the content's current top, so repeated layout passes are idempotent. WPT: align-out-of-flow-only-content passes (538 pass / 53 fail). Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
An inline-level absolutely positioned box whose parent lays out only block-level children has no line box to take its static position from. It now opens a hypothetical empty line at its block position: preceding floats shorten that line and text-align places the static position on it. In a right-to-left block the box's right margin edge meets the position (CSS 2.2 10.3.7). Positions recorded by laid-out lines keep anchoring the box's left edge: those lines keep their items in left-to-right order, so the content that follows the box is on its right. WPT: inline-level-absolute-in-block-level-context-001..012 pass (548 pass / 43 fail). Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
A sole text run is widened to the line it was offered so text-align has room to work in. When the block holding it then autosized to its content, the run kept that width, and the flex automatic minimum size, measured from the children's extents, grew the item back to the full line: every block item carrying one line of text filled its flex row. Widened runs now span the block's final content width. A document's root element fills the initial containing block whatever its display (CSS 2.2 10.3.3); a flex html root no longer shrinks to its items. Native roots keep sizing to their content. WPT: 548 pass / 43 fail, unchanged; the rows of clip-text-stacking-context-child-002 that depend on it now match. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
A float that followed inline content started below the content's line. CSS 2.2 9.5.1 puts a float that fits beside the content of the current line at the top of that line, and the line's content flows beside it. When a run ends at a float without a line break, fits on one line and leaves room for the float, the float now moves ahead of the run: it is placed at the run's top and the run is laid out again beside it, taking in any content that follows the float. WPT: clip-text-stacking-context-child-002 passes (549 pass / 42 fail). Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
margin-trim was only applied to block containers. A flex container now zeroes, after building its lines, the main-axis margins of each line's first and last item against a trimmed edge, and the cross-axis margins of the items in the first and last line; line sizes are recomputed before flexing, alignment and autosizing. A grid container zeroes the margins of items in its first and last rows and columns against trimmed edges before sizing tracks. Flags map to physical sides through the container's writing mode and direction, so reversed directions and wrap-reverse find the right items. Trimmed margins are restored when the pass ends. positionLineChildren's start-side computation moves into flexStartSides so both use it. WPT: 18 margin-trim flex and grid tests pass (595 pass / 59 fail). Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
transform: inherit was parsed as a transform list, found nothing and cleared the transform. It now takes the parent's computed rotation, translation, scale and outer-axis translation. WPT: css-transform-inherit-scale passes (596 pass / 58 fail). Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
The selector engine knew only the descendant and child combinators; a + or ~ was read as a tag name and the rule never matched. Selector plans now record a sibling relation per part: + requires the previous element sibling to match the part on its left, ~ any earlier element sibling. Text nodes and generated content are not element siblings. Restyling follows: a class change touching a key used left of a + or ~ restyles the siblings after the node, and inserting, moving or removing a node restyles the siblings after its old and new positions. All of it is skipped unless some rule uses a sibling combinator. The static selector plans generated by the geatsc build carry the same relation, as they share the selector plan cache with runtime rules. WPT: background-clip-padding-box-with-border-radius passes; its reference relied on div + div (597 pass / 57 fail). Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
aspect-ratio: auto <ratio> applies the ratio to the content box whatever box-sizing says (CSS Sizing 4); the transfer used the border box when box-sizing was border-box. The stored ratio's sign already marks the auto form. A flex item's content size suggestion is now clamped by its definite minimum and maximum cross sizes converted through its preferred aspect ratio (CSS Flexbox 4.5): a min-height widens a row item, a max-width caps a column item whose content is taller. WPT: flex-aspect-ratio-025 and -026 pass (599 pass / 55 fail). Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
When a block formatting context contains a float anywhere, its normal blocks, including those inside non-BFC wrappers, are placed by the float path, which ignored auto margins: a single float left every margin: 0 auto block in that context at the start edge. Block placement now shares blockInlineOffset between the block and float paths, and a block formatting context beside floats centers with auto margins in the space between them. WPT: unchanged (599 pass / 55 fail). Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
A text node that is a flex item was always ink-centred in its line advance, a deliberate optical-centring choice for UI boxes. CSS wraps bare flex text in an anonymous block, so it sits on its baseline exactly like the same text in block flow; the engine drew it 1-2px lower. Flex text items now get the baseline flag unless the container centres them vertically (align-items/align-self: center in a row, justify-content: center in a column), which keeps optical centring where the author asked for centring: buttons and labels.

Declared and laid-out width/height were int16: `width: 40000px` wrapped to a negative length, so a huge box scaled down by a transform lost its content and painted as its borders alone. ComputedStyle::width/height, LayoutBox::width/height and previous_width/height are now int32, bounded by kMaxLayoutExtent (2^24, exact in the float projection math); the layout writes that clamped to int16 use clampLayoutExtent instead. Display commands still carry int16 rects. Rather than grow every command, recording saturates what overflows: overflow clip shapes and FillRect/SetAlpha rects clamp to the int16 range, which no screen exceeds, and a transformed border ring whose local box passes int16 or whose ring passes 255px paints as four transformed side quads.

Store the saved width in int32_t in ColumnWidthScope.
This PR widens layout.width to int32_t. ColumnWidthScope still saves the width in an int16_t and writes it back in the destructor. For a multicol container wider than 32767 px, the destructor restores a truncated width after layoutColumns or repositionChildren runs. This is the 16-bit narrowing that the 32-bit box change set out to remove.

Clear line-clamp state when the container stops clamping.
When clampsLines(node) becomes false, both layout paths skip applyLineClamp, so stale line_clamp_hidden and line_clamp_lines values remain. Rendering and hit testing continue to reject hidden descendants. A moved descendant can retain the same stale state.
Use a separate ownership marker. Do not store it in line_clamp_hidden, because existing assignments overwrite that field. Reset each node’s clamp state before layout, then clear owned descendants when clamping stops.

Fix the division by zero in BlendDrawer::setSat when all channels are equal.
The guard if (lo == hi) does not detect an achromatic color. The index loop uses < for lo and >= for hi. For an input such as {0.5, 0.5, 0.5}, the loop ends with lo = 0 and hi = 2, so the guard does not return. Then c[hi] - c[lo] is 0, and c[mid] becomes NaN (0/0).
Triggers:
- Mode 12 (
hue) callssetSat(out, sat(cb))without = cs. A grey gradient stop makescsachromatic. - Mode 13 (
saturation) callssetSatwithout = cb. A grey backdrop makescbachromatic.
White, black and grey are common values for stops and backdrops. The NaN then passes through setLum. Line 5579 casts it with static_cast<int>, which is undefined behavior. The result is wrong pixel values in the blended layer.
Compare the channel values, not the indices:
🐛 Proposed fix
- if (lo == hi) { c[0] = c[1] = c[2] = 0.0f; return; }
+ if (c[hi] - c[lo] <= 0.0f) { c[0] = c[1] = c[2] = 0.0f; return; }
const int mid = 3 - lo - hi;lo == hi cannot occur after this loop for three channels, so the new check also covers that case.

Accept a color-only text-emphasis shorthand.
The text-emphasis shorthand grammar is <'text-emphasis-style'> || <'text-emphasis-color'>. A color alone, such as text-emphasis: red, is valid. It sets the style to its initial value none.
The current code has two problems:
- The shorthand rejects a color-only value. The check
if (mark < 0 && open < 0) return 0;runs for the shorthand as well as the style longhand. - As a result, the whole declaration is dropped. The color is not applied, and an earlier mark set by the cascade is not reset.

Trigger sibling restyles only when a sibling key is added or removed.
classTokensTouchSiblingSelectors returns true in two cases:
- The node's tag is in
siblingTags. - Any old or current class is in
siblingClasses.
A class mutation cannot change the tag. It also cannot change a class that is present both before and after the mutation. Neither case can change a + or ~ match. The function still calls recomputeSiblingsFrom(next_sibling), which restyles the full subtree of every following sibling.
Example: a common separator rule is li + li { border-top: ... }. With that rule, each .active toggle on any li restyles every later li subtree. Outside a mount batch, this is O(siblings × subtree) per toggle. Long lists on embedded targets pay this cost on every interaction.
Test only the symmetric difference of the old and new class sets. The tag parameter is then no longer needed. Update the call at Line 16796 to match.

Limit the native shadow rounded rect to the int16 range, or fall back to spans.
appendShadowRoundedRect writes x, y, w and h into the int16 fields cmd->bx/by/bw/bh, fillRoundedRect.* and strokeRoundedRect.*. It does not saturate these values first. Box dimensions are now 32-bit, so a tall card can exceed 32767 px. For example, a page wrapper with an opaque background, box-shadow: 0 4px 0 #000 and height: 40000px does this.
outerShadowKnockoutHiddenreturns true for this box.shadowContourInside(shape, box)fails because of the offset.- The command therefore records
h = 40004, which wraps to a negative int16. - The shadow is dropped, or painted with wrong geometry, on every refresh.
The span path does not have this problem, because appendFillRectRaw now calls saturateRect16.
A fix: in recordOuterBoxShadow, turn off the native path when the shadow contour, including blur, goes outside the int16 range.
Proposed fix
bool native = outerShadowKnockoutHidden(node, parentAlpha);
for (int i = 0; i < 4; ++i) native &= std::fabs(shape.rx[i] - shape.ry[i]) < 0.5f;

Byte layout is unchanged. - Keep the new text-emphasis, text-align-last, vertical-align and line-clamp fields outside main's feature-flag guards. - Read static_block_start/axis through layoutState() in the hypothetical-line and align-self static position code. - Guard margin-trim writes with GEA_CSS_MARGINS / GEA_CSS_MARGIN_AUTO and the sticky root-scroll counter with GEA_REFRESH_PERF.

Keep background-layer fields independent of gradient support.
The new fields are inside the gradient feature block. With both gradient macros disabled, unguarded comparisons, setters, accessors, and border-image consumers can reference missing members.
Move these fields to the GEA_CSS_BACKGROUND_LAYERS block. Provide static defaults only when that background-layer feature is disabled. Do not add defaults to the gradient #else branch while background-layer setters remain enabled.

replicateColumns() appends translated copies outside the recorded node ranges. tryReprojectTransformed() patches only nodeDrawStart/nodeDrawEnd ranges, so copied columns can retain the previous frame’s corners.

Preserve border widths when applying none, and record none in the border shorthand.
style.cpp:8729 stores zero as the side width. A later border-style: solid update changes only the relief, so the declared width cannot be restored. CSS requires the earlier width to remain effective when the final style is not none.
compileBorderShorthandValue also sets border: none and border: hidden to width 0 but leaves compiled.values[2] at 0. The shorthand then records a normal relief. A later border-width can therefore enable the border, although CSS keeps the border disabled.
Keep the declared width independent from the relief. Resolve none and hidden to an effective width of zero when the width is read, or recompute the effective width when either property changes. Also record kBorderStyleNone for shorthand none and hidden.
Suggested shorthand fix
- if (noStroke) compiled.lengths[0] = {0.0f, CssLengthUnit::Px};
+ if (noStroke) {
+ compiled.lengths[0] = {0.0f, CssLengthUnit::Px};
+ compiled.values[2] = kBorderStyleNone;
