CSS Conditional Rules Module Level 3

https://www.w3.org/TR/2020/CR-css-conditional-3-20201208/

Abstract

This module contains the features of CSS for conditional processing of parts of style sheets, conditioned on capabilities of the processor or the document the style sheet is being applied to. It includes and extends the functionality of CSS level 2 [CSS21], which builds on CSS level 1 [CSS1]. The main extensions compared to level 2 are allowing nesting of certain at-rules inside @media, and the addition of the @supports rule for conditional processing.  CSS is a language for describing the rendering of structured documents (such as HTML and XML) on screen, on paper, etc.
