CSS Counter Styles

The @counter-style CSS at-rule allows custom counter styles to be defined. A @counter-style rule defines how to convert a counter value into a string representation.

Scoped Styles: the @scope rule

Allows CSS rules to be scoped to part of the document, with upper and lower limits described by selectors.
