LibWeb keeps growing and the Web namespace is filling up fast.
Let's put DOM stuff into Web::DOM, just like we already started doing
with SVG stuff in Web::SVG.
"width: 500" is not a valid CSS property in standards mode and should
be ignored.
To plumb the quirks-mode flag into CSS parsing, this patch adds a new
CSS::ParsingContext object that must be passed to the CSS parser.
Currently it only allows you to check the quirks-mode flag. In the
future it will be a good place to put additional information needed
for things like relative URL resolution, etc.
This narrows <div class=parser> on ACID2 to the correct width. :^)
Instead of storing the three-part specificy for every selector,
just mash them together into a 32-bit value instead.
This saves both space and time, and matches the behavior of other
browser engines.
We now sort the matched rules by the specificity of the first selector
in them. This is not perfect, since a rule can have multiple selectors,
but it is a nice chin-related progression on ACID2. :^)
This patch introduces support for more than just "absolute px" units in
our Length class. It now also supports "em" and "rem", which are units
relative to the font-size of the current layout node and the <html>
element's layout node respectively.
Until now we would simply apply stylesheets in the order they finished
loading. This patch adds a StyleSheetList object that hangs off of each
Document and contains all the style sheets in document order.
There's still a lot of work to do for a proper cascade, but at least
this makes us consistently wrong every time. :^)
This makes it possible to write shorter CSS. Instead of writing
.foo {
border-width: 3px;
border-style: solid;
border-color: blue;
}
it is now possible to write
.foo {
border: 3px solid blue;
}
while the order of values is irrelevant.
Currently only the basic values are supported. More values should be
added in the future.
Three more value specific parse functions were added:
parse_line_width, parse_color, and parse_line_style
Additionally a few test cases were added to borders.html.
