Using utility variants

Learn how to override existing utilities based on the user's screen size or other factors, such as hover states.

Target media queries

You can combine responsive breakpoints like sm:zi-*, md:zi-*, lg:zi-*, and xxl:zi-* to allow targeting specific utilities in different viewports.

Targeting hover states
