Tim Ledbetter	e502f19fa7	LibWeb: Implement the animation-composition property	2025-09-19 10:10:05 +01:00
Callum Law	968a8e618c	LibWeb: Use computed font style when parsing font-style descriptor ... This means we now properly support relative units and clamping for calcs in font-style descriptors	2025-09-19 10:06:33 +01:00
Callum Law	e17d91780d	LibWeb: Clamp computed value for font-style oblique angle ... Values outside [-90deg,90deg] are invalid and should be clamped	2025-09-19 10:06:33 +01:00
Callum Law	dc41d045d8	LibWeb: Store font-style in ComputedProperties in computed form	2025-09-19 10:06:33 +01:00
Callum Law	10793aef56	LibWeb: Move to_font_slope from StyleValue to FontStyleStyleValue ... This method only operated on `FontStyleStyleValue`s anyway so this is a better place to have it	2025-09-19 10:06:33 +01:00
Callum Law	425b7de44a	LibWeb: Use compute_font_width for font-width descriptor ... This allows us to remove `StyleValue::to_font_width`	2025-09-19 10:06:33 +01:00
Callum Law	335c8c7ffb	LibWeb: Store font-width in ComputedProperties in computed form	2025-09-19 10:06:33 +01:00
Callum Law	073d10c6d1	LibWeb: Clamp dimension percentage values to the specified percentage ... Previously we would clamp the percentage value to the allowed range for canonical dimension values rather than the percentage value. Also fixes an issue where we would clamp pure percentages (i.e. percentages that don't have a hint) against the allowed values for the first dimension we checked (i.e. angle)	2025-09-19 10:06:33 +01:00
Callum Law	b52525b454	LibWeb: Convert font-width percentages to keywords when serializing font	2025-09-19 10:06:33 +01:00
Callum Law	45a4e9cd0f	LibWeb: Use compute_font_weight for font-weight descriptor ... This allows us to remove `StyleValue::to_font_weight`	2025-09-19 10:06:33 +01:00
Callum Law	44eaa7ad98	LibWeb: Avoid overwriting non-animated font-weight when computing font ... Previously if we would overwrite the non-animated font-size with the animated font-size if it was set. Loses us 2 WPT tests but this is in line with other browsers	2025-09-19 10:06:33 +01:00
Callum Law	39484e2027	LibWeb: Store font-weight in ComputedProperties in computed form ... We now also more closely follow the spec when computing values for font-weight and we now: - Support relative lengths in `calc()`s - Properly clamp `calc()`s - Support relative keywords (e.g. lighter, bolder) - Respect that font-weight can be a non-integer number. This does expose a few false positives in the font-weight-computed.html WPT test. This is because we don't recompute non-inherited font-weight within `recompute_inherited_style` which means that relative keyword values can fall out of sync with their parent's value. These previously passed as we treated `bolder` and `lighter` as aliases for `bold` and `normal` respectively.	2025-09-19 10:06:33 +01:00
Callum Law	cfbe0244d4	LibWeb: Use computed value of font-size in keyframes ... Remaining test failures in font-size-interpolation-00* are either: - Rounding of font-size to CSSPixels when setting the expected value - Not clamping negative values from the point of view of getComputedStyle (used values are still clamped)	2025-09-19 10:06:33 +01:00
Callum Law	64d2f0d55a	LibWeb: Avoid overwriting non-animated font-size when computing font ... Previously if we would overwrite the non-animated font-size with the animated font-size if it was set. Gains us 8 WPT tests and means we now fail 9 others in line with other browsers.	2025-09-19 10:06:33 +01:00
Callum Law	c6049e6853	LibWeb: Remove StyleComputer::root_element_font_metrics_for_element ... This method is now unused so can be removed	2025-09-19 10:06:33 +01:00
Callum Law	e9faf056f1	LibWeb: Decouple font-size computation from compute_font_for_syle_values ... There are other places we want to convert font-size into it's computed form than just when we are loading the font (e.g. computing keyframes). Gains us 36 WPT passes as we now correctly clamp negative calc values.	2025-09-19 10:06:33 +01:00
Callum Law	d6754307f9	LibWeb: Separate relative sizes from absolute_size_mapping ... Having relative sizes handled in this function was misleading	2025-09-19 10:06:33 +01:00
Callum Law	1ca511b627	LibWeb: Correctly resolve percentages against relative lengths in calcs ... Previously we would always assume the percentage was 100%	2025-09-19 10:06:33 +01:00
Callum Law	b80e6a4d30	LibWeb: Rename get_inherit_value to get_non_animated_inherit_value ... This more acurately represents what it does.	2025-09-19 10:06:33 +01:00
Tim Ledbetter	9b15517052	LibWeb: Apply composite operator to keyframe effects	2025-09-18 16:46:06 +01:00
Callum Law	004bd3dc8f	LibWeb: Clamp calc()'d shadow blur radius to positive values	2025-09-18 15:21:22 +01:00
Callum Law	19e3ddc0c6	LibWeb: Simplify parse_single_shadow_value ... The `possibly_dynamic_length` function was unnecessary and can be replaced with the standard `parse_length_value`	2025-09-18 15:21:22 +01:00
Callum Law	c3a78d2884	LibWeb: Don't include spread distance when serializing text-shadow ... We shouldn't include spread distance when serializing `text-shadow` as it is not supported unlike `box-shadow` - to achieve this we store whether this is a text or box shadow within the ShadowStyleValue and serialize appropriately.	2025-09-18 15:21:22 +01:00
Callum Law	1ac7b47764	LibWeb: Disallow spread distance value when parsing text-shadow ... `text-shadow` does not support setting a value for spread distance unlike `box-shadow`.	2025-09-18 15:21:22 +01:00
Sam Atkins	95aceb6ec9	LibWeb: Store custom properties in an OrderedHashMap ... We are expected to preserve their order within a style declaration, so let's do that. Passes 1 tracked WPT subtest.	2025-09-18 14:59:14 +02:00
luizgfc	bcbbecff9f	LibWeb: Correctly handle properties on CSS declaration serialization	2025-09-18 09:25:23 +01:00

Callum Law	34b8947ca0	LibWeb: Support text-underline-position: under	2025-09-15 15:24:20 +01:00
Callum Law	b0e3af7d10	LibWeb: Parse text-underline-position property ... This introduces the `TextUnderlinePositionStyleValue` class, it is possible to represent `text-underline-position` as a `StyleValueList` but would have required ugly workarounds for either serialization or in `ComputedProperties::text_underline_position`	2025-09-15 15:24:20 +01:00
Callum Law	a6812e1005	LibWeb: Store parsed shorthands in canonical order	2025-09-15 15:24:20 +01:00

Sam Atkins	5904694844	LibWeb/CSS: Implement CSSImageValue and reify images as it ... This is specced to be opaque, so there's not much to it.	2025-09-15 08:47:10 +01:00
Callum Law	50239b58aa	LibWeb: Reset border-image to initial value when using border ... Also includes associated handling for serialization of the `border` shorthand.	2025-09-15 08:42:22 +01:00
Callum Law	588c611e7e	LibWeb: Use correct initial value for border-image ... Omitting the `/`s meant that `1` and `0` were parsed as part of border-slice instead of their intended values. No functional changes but this will be relied on in a later commit.	2025-09-15 08:42:22 +01:00
MFMF-EGY	fff09ed330	LibWeb: Handle interpolation of BorderRadius style value type	2025-09-14 16:49:20 +01:00
Marcos Del Sol Vives	40792aa85d	LibWeb/CSS: Fix compilation with CSS_TRANSITIONS_DEBUG ... A new parameter was added to Web::CSS::StyleValue::to_string() in PR #2820 but this debug message was never updated. If CSS_TRANSITIONS_DEBUG was enabled, compilation would fail.	2025-09-13 23:33:57 +02:00
Tim Ledbetter	19577b966e	LibWeb: Implement interpolation of border-image-slice style values	2025-09-13 12:05:19 +02:00
Callum Law	a805635e40	LibWeb: Compute dimension percentage mix as percentage where applicable ... When we have a `calc` which is a mix of a dimension and a percentage, we should use the percentage alone for the computed value if the dimension component is 0 e.g. `calc(50% + 0px)` should use `50%` as it's computed value.	2025-09-12 15:04:30 +01:00
Nico Weber	9272df7a86	Everywhere: Fix a few unreachable-return / unreachable-break warnings ... I was playing with clang's -Wunreachable-code-aggressive a bit. This fixes a handful uncontroversial things it flags. No behavior change.	2025-09-12 14:33:14 +01:00
Sam Atkins	a139ad1c44	LibWeb/CSS: Implement CSSNumericValue.to() ... Tries to convert the CSSNumericValue to a CSSUnitValue with the given unit. This gets us the remaining 11 WPT subtests for this method.	2025-09-12 13:45:41 +02:00
