Summary

The @media CSS at-rule associates a set of nested statements, in a CSS block that is delimited by curly braces, with a condition defined by a media query. The @media at-rule may be used not only at the top level of a CSS, but also inside any CSS conditional-group at-rule.

The @media at-rule can be accessed via the CSS object model interface CSSMediaRule.
