CSS3 Border-radius (rounded corners)

Method of making the border corners round. Covers support for the shorthand `border-radius` as well as the long-hand properties (e.g. `border-top-left-radius`)

:is() CSS pseudo-class

The `:is()` (formerly `:matches()`, formerly `:any()`) pseudo-class checks whether the element at its position in the outer selector matches any of the selectors in its selector list. It's useful syntactic sugar that allows you to avoid writing out all the combinations manually as separate selectors. The effect is similar to nesting in Sass and most other CSS preprocessors.

CSS zoom

Method of scaling content while also affecting layout.

CSS font-smooth

Controls the application of anti-aliasing when fonts are rendered.

CSS outline properties

The CSS outline properties draw a border around an element that does not affect layout, making it ideal for highlighting. This covers the `outline` shorthand, as well as `outline-width`, `outline-style`, `outline-color` and `outline-offset`.
