through display list building.
The old `flow_origin` concept was ill-defined (sometimes the border box
plus the flow origin, sometimes including horizontal margins and
sometimes not, sometimes including relative position and sometimes not),
leading to brittleness and test failures. This commit reworks the logic
to always pass border box origins in during display list building.
This does not implement any notion of CSSStyleDeclaration objects that do not have an owning element; there's no actual CSS object model in play here. This does support setting and getting properties of the style attribute for HTMLElement, and tries to implement the ambiguous CSS value serialization spec.
I'm not sure how we want to handle Linux cursors, and GLFW has no
ability to set cursors (short of disabling it and managing it yourself).
If you test this in the wild you will probably hit #4357 until that PR lands.
We can reset `<input type=text>` fields! I wish I could've done something with checkboxes, but unfortunately, that's it for now.
In addition to that, this PR implements `HTMLInputAttribute.defaultValue`, updates wpt-test to expect passing tests as a result of that implementation, and fixes an index error crash with text inputs.
edit: also includes an html example where one may lazily watch form resets in action: ` tests/html/form_reset_handsfree.html`
This patch provides some of the groundwork for column spans greater than
1. It implements the column-span CSS property (prefixed so as not to be
exposed to content) as well as the corresponding colspan attribute;
although the former is not well-specified outside of CSS multi-column
layout, INTRINSIC refers to it. Although width is distributed to
spanning columns, they do not yet contribute minimum and preferred
widths; this will be implemented in a follow-up.
Additionally, this patch cleans up some miscellaneous formatting issues
and improves the handling of table rowgroups.
Additionally, this patch cleans up some miscellaneous formatting issues
and refactors files in `layout/css/` somewhat to eliminate needless
levels of indirection. It also fixes our handling of presentational
hints that only apply if border is nonzero.
