CSS and UI
CSS symbols() The CSS symbols() function lets authors define a counter style inline instead of first declaring a named @counter-style at-rule. It builds an anonymous counter style from a list of string symbols plus an optional counting system (cyclic, numeric, alphabetic, symbolic, or fixed), and is accepted as the counter style in list-style-type, the list-style shorthand, counter(), and counters().
CSS corner shorthand properties
Implements the CSS corner shorthand and per-corner sub-shorthands (corner-top-left, corner-top-right, corner-bottom-left, corner-bottom-right) as well as physical (corner-top, corner-bottom) and logical (corner-block-start, corner-block-end, etc.) edge shorthands. These allow setting both border-radius and corner-shape for individual corners in a single declaration. Additionally, corners is retained as a compat alias for the corner shorthand.
This feature also includes caching controls. By default, each random() function resolves to a new, distinct value. Web authors can override this default by passing a <random-key> value as the function's first argument to control how random values are shared across properties and elements.
CSS text-decoration-skip-spaces
The text-decoration-skip-spaces CSS property controls whether text decoration lines (for example, underlines, overlines, and line-throughs) skip over whitespace characters. This allows authors to prevent decorations from being drawn under spaces, which is often more visually appealing.
CSS margin-trim
The margin-trim CSS property may be used to omit margins before or after the first or last child of a container. This is supported on regular block containers and multicol containers.
Note: A previous version of the spec also applied this for flex and grid containers, but this has been removed.
