We have a slightly odd setup here. TransformationStyleValue reifies as a
single CSSTransformComponent. It's StyleValueList that actually reifies
as a CSSTransformValue - but only if it only contains
TransformationStyleValues.
+79 WPT subtests.
This is the final CSSStyleValue class used by the per-property test
harness, so those now actually run instead of throwing an exception on
load. 🎉
+39 WPT subtests. (Plus however many from the per-property tests finally
running.)
The two failing serialization tests are also failed by Safari in exactly
the same way, so that seems more like a spec issue. (The spec is
incomplete in quite a few places.) The failing subtest for toMatrix() is
also a spec issue: is2D is handled oddly by CSSMatrixComponent and this
subtest fails because of the `matrix` getter, which is unspecified. See
https://github.com/w3c/css-houdini-drafts/issues/1155 for details.
DOMMatrix.to_string() throws exceptions if any of its values are
non-finite. This ends up affecting CSSStyleValue because its subclass
CSSTransformValue (which is about to be added) serializes
CSSTransformComponents, and one of those is CSSMatrixComponent, which
calls DOMMatrix.to_string().
This is all quite unfortunate, and because at the time the spec for
DOMMatrix was written, CSS couldn't represent NaN or infinity. That's
no longer true, so I'm hoping the spec can be updated and this can be
reverted. https://github.com/w3c/fxtf-drafts/issues/611
Equivalent to the perspective() transform function.
+34 WPT subtests, and the transformvalue-normalization test now runs to
completion instead of throwing an error - though its cases still fail
until CSSTransformValue is implemented.
This is a base type for the various transform functions.
CSSMatrixComponent's to_string() can throw exceptions, so to_string() is
implemented that way. https://github.com/w3c/fxtf-drafts/issues/611
+9 WPT subtests.
Opacity values are unique in that the range which calculated and
interpolated values should be clamped to [0,1] is different from the
range of allowed values [-∞,∞].
This fixes 28 WPT tests that were regressed in #6112
We now:
- Serialize longhands in the correct order
- Support serializing multiple values
- Include default longhands where required (to distinguish
animation-name from that longhand).
We were unnecessarily computing property values within
`collect_animation_into` which we can avoid by ensuring that all calls
to `collect_animation_into` happen after property values are computed.
This change adds the allowed angle range to the `font-style` property
definition. This allows these angles to be clamped after interpolation.
Ideally, the generator should be updated so that we can specify the
angle is in degrees. This would allow us to make use of this
information during parsing, which we can't do currently because we
don't know what the unit is. Using this value for interpolation
purposes is fine because the angle has been converted to its canonical
unit by this point.
We now fail a few more tests in properties-value-inherit-001.txt as we
no longer overwrite the non-animated value of `line-height` with the
animated value, this is in line with other major browsers.
We were already doing this within `compute_property_values` where
we resolved most relative lengths but the remainder was instead
incorrectly using the font's line-spacing
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)
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
