Having these in here was a hack to support the other hack of making
media-queries use StyleValues. Now they don't do that, so we can remove
these again and keep things hygienic.
This allows supporting websites to use a light or dark theme to match
our desktop theme, without being limited to palette colors. This can be
overridden with the `WebContentServer::set_preferred_color_scheme()` IPC
call.
The `currentcolor` identifier represents the current value of the
`color` property. This is the default value for `border-color` and
`text-decoration-color`, and is generally useful to have. :^)
This is just to make the CSS parser stop whining when it encounters some
very common properties and identifiers. More work will be required to
actually support these things. :^)
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 resolves the three sub-properties, appearing in any order:
- list-style-image
- list-style-position
- list-style-type
Added `list-style-position` values to support this, though they are not
yet used in rendering.
This doesn't exactly do what you would think from its name: It surely
adds an extra leading zero to the front of a number, but only if the
number is less than 10. CSS is weird sometimes.
