- More combinations of values
- Testing a font (Liberation Serif) which has multiple faces
- Add calc() tests for font-size and weight
- Check fallback when a font isn't available
While I was at it, reorganized the file so the CSS is inline - this
keeps it close to the relevant test case.
This is not just moving the code from StyleResolver to Parser. The logic
has changed to allow for the `flex-basis` to come before or after the
`flex-grow/shrink` values, as well as handle the special one-value
cases.
Also added test cases to flex.html to check the parsing. It does parse
correctly, but elements with `flex-basis: auto` do not calculate their
width correctly.
Modified text-decoration.html to better test that the values can be in
any order, and that it adopts the color from the `color` property if no
decoration color is specified. Right now, it always does because we do
not support a different decoration color. Later, we need to support the
`currentcolor` special CSS value for this purpose.
Yes, the name is silly, but it's a StyleValue for list-style, so...
yeah. :^)
Since `list-style-type` and `list-style-image` can both have `none` as a
value, and can appear in any order, we have to handle it separately, and
then assign either or both of those to `none` depending on how many
`none`s there are, and whether those sub-properties already have values.
Added some extra test cases to lists.html to cover list-style-image and
list-style-position parts of the list-style shorthand, and the `none`
values.
This one represents one secton of a `background` property, since it can
have multiple background values separated by commas. Eventually, we will
represent that as a List of BackgroundStyleValues.
Also modified some background-foo properties in StyleResolver so that
the is_background_x() functions could be removed.
I realized that our handling of var() in shorthand properties is wrong,
so have been removing the is_builtin_or_dynamic() calls from the parsing
code for shorthands. This broke our var() test page, so I have replaced
the use of 'background' with 'background-color' there.
After working with the code for a while, it makes more sense to put all
the parsing in Parser, instead of some of it living in StyleResolver.
That means our current ValueListStyleValue needs to be replaced with
specific StyleValue types for the properties that are shorthands or
otherwise combine several values together.
Here we implement FontStyleProperty, which represents a `font` CSS
property.
Also adjusted the fonts.html test page so that font-weights are featured
in test cases without things we do not yet support.
Previously, it was a big list of test pages in no particular order, and
it was hard to find anything. This commit breaks it up into sections,
and renames some of the links to be more consistent.
The categories are slightly arbitrary, and I'm sure everyone will have a
different opinion on what they should be, and which links should go
where. But hopefully we can all agree that this is an improvement!
This also wraps the list into multiple columns on browsers that support
it, which unfortunately does NOT include Browser. :^( But hey, once we
do it'll be good!
Also added css-import.html, which tests the 3 syntax variations on
`@import` statements. Note that the optional media-query parameter to
`@import` is not handled yet.
This detects and resolves these in the text-decoration property, in any
order:
- text-decoration-color
- text-decoration-line
- text-decoration-style
Only the solid underline renders, but all three sub-properties are
assigned correctly.
The font property now resolves into its various parts:
- font-family
- font-weight
- font-size
- font-style
- line-height
The font-variant and font-stretch parts are left unparsed since LibWeb
doesn't know how to render those.
Added `fonts.html` as a test for various forms of `font` declarations,
based on the examples in the spec.
This was broken when we switched away from using StringStyleValues.
While I was at it, I have implemented hsl/a() and the percentage
syntax for rgb/a().
As a bonus, added `colors.html` as a test page for the various CSS
color syntaxes, since nothing was testing rgb() or rgba() before.
Much of the parsing code in LibGFX/Color.h seems to be centered
around CSS color values, but this is not used by the new Parser.
(And can't be used, because it requires a String value and we have
a list of Tokens of some kind instead.) Maybe that should be removed
from there when the new CSS parser is operational.
Rather than parsing the selector every time we want to check it, we
now parse it once at the beginning.
A bonus effect of this is that we now support a selector list in
:not(), instead of just a single selector, though only when using
the new parser.
This adds test pages for border-radius, CSS custom properties and
flexboxes to the default page in the Browser.
I used those files to develop said features and they can be of use
when debugging in the future or just to showcase those features.
This impl is *extremely* simple, and is missing a lot of things, it's
also not particularly spec-compliant in some places, but it's definitely
a start :^)
The WebSocket bindings match the original specification from the
WHATWG living standard, but do not match the later update of the
standard that involves FETCH. The FETCH update will be handled later
since the changes would also affect XMLHttpRequest.
