CSS @when / @else conditional rules

Last updated on : 2023-03-20

Note:
CSS @when / @else conditional rules shows a browser compatibility score of 0. This is a collective score out of 100 to represent browser support of a web technology. The higher this score is, the greater is the browser compatibility. The browser compatibility score is not a 100% reflection for every browser and the web technology support. However, it does give you an estimate on how much you should rely on a particular web technology in terms of browser compatibility.

Overview

A new syntax and condition system has been added that allows easy creation of advanced, media-conditioned stylesheets. The syntax also allows for easier creation of mutually exclusive portions of CSS such as making a set of media queries be written as a single @else if block
