Parse out the font-family, font-size and font-weight values from CSS
and use them to perform a kinda-best-effort lookup against the system
font library.
We also now handle standard font names like "sans-serif", "monospace"
and others.
This is definitely not fully-featured, but basically we now handle
the clear property by forcing the cleared box below the bottom-most
floated box on the relevant side.
Instead of doing a CSS property lookup for the line style of each
border edge during paint, we now cache the final CSS::LineStyle to use
in the Layout::BorderData.
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.
To get the expected behavior for <center>, we needed a special text
alignment mode that centers block-level elements (and not just line
box fragments.)
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.
This was a confusing bug: ImageStyleValue loaded its image resource as
a Generic resource, while HTMLImageElement loaded as Image.
This patch fixes the issue and adds an assertion to verify that we only
share resources that have the same C++ client class type.
Many properties can now have percentage values that get resolved in
layout. The reference value (what is this a percentage *of*?) differs
per property, so I've added a helper where you provide a reference
value as an added parameter to the existing length_or_fallback().
This momentarily handles the CSS property "position: absolute;" in
combination with the properties "top" and "left", so that elements can
be placed anywhere on the page independently from their parents.
Statically positioned elements ignore absolute positioned elements when
calculating their position as they don't take up space.
