Conditional styles

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

Breakpoint variant

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

<div class="ff-s md:ff-m ..."></div>

Hover variant

Alternatively, you can apply :hover by using h:ff-* utility to override elements and change their values when hovering over them.

<div class="ff-s h:ff-m ..."></div>
