The `start` and `end` value set the text alignment based on the computed
value of `direction`. The default value of `text-align` is now `start`
instead of `left`.
This is `counter(name, style?)` or `counters(name, link, style?)`. The
difference being, `counter()` matches only the nearest level (eg, "1"),
and `counters()` combines all the levels in the tree (eg, "3.4.1").
These control the state of CSS counters.
Parsing code for `reversed(counter-name)` is implemented, but disabled
for now until we are able to resolve values for those.
In the upcoming commits where we properly handle transformation
interpolation, it actually becomes easier to change this back to custom,
so lets do that since its more correct anyways.
This also changes transform's animation-type to by-computed-value. It is
far easier to handle since we switch on StyleValue::type(), and it might
be the case that this applies to all custom animated properties and we
don't need "custom" at all, but let's wait until we get to those
properties to make that decision.
This allows positioning a child SVG relative to its parent SVG.
Note: These have been implemented as CSS properties as in SVG 2, these
are geometry properties that can be used in CSS (see
https://www.w3.org/TR/SVG/geometry.html), but there is not much browser
support for this. It is nicer to implement than the ad-hoc SVG
attribute parsing though, so I feel it may make sense to port the rest
of the attributes specified here (which should fix some issues with
viewport relative sizes).
Implemented by adding the extra 3-value syntax as its own case and only
running it when parsing background-position. I'm sure it could be
implemented in a smarter way but this is still a bunch less code than
before. :^)
This means `object-position` will no longer incorrectly accept the
3-value background-position syntax.
Remove the now-ambiguous and unused `position` enum while we're at it.
(This enum only existed as a hack.)
This patch adds the 'object-position' CSS property description to the
json for code generation.
Also the 'position' enum is added. The values of this enum are the
valid inputs to the object-position property from CSS Values-4.
The postitioning enum values are used by the position CSS property.
Unfortunately, the prior naming clashes with the CSS Values-4 type
named position, which will be implemented in a later commit.
These three are the ones that ShorthandStyleValue uses to serialize
`grid`, so let's use them here.
The spec also mentions `grid-auto-*` properties as being set by `grid`,
but I'll leave that for someone who understands grid better.
This adds initial support for `open-quote`, `close-quote`,
`no-open-quote` and `no-close-quote`. We don't yet track the "nesting
level" so we always use the first pair of quotes from the `quotes`
property.
This one is a bit fun because it can be `add(<integer>)` or `auto-add`,
but children have to inherit the computed value not the specified one.
We also have to compute it before computing the font-size, because of
`font-size: math` which will be implemented later.
And treat them as "auto" for now, per CSS-SIZING-3, with a FIXME about
supporting more layout directions.
This fixes an issue on MDN where `height: max-content` was not
overriding height from non-CSS presentational hints.
CSS-ALIGN-3 tells us that `normal` behavior inside flex containers is
simply to behave as `stretch` so this patch makes them behave the same
inside FFC.
Furthermore, we change the `align-items` initial value to `normal`,
matching other engines.
