Variants

Prefix any class with a variant to apply it only under that condition. Variants stack, as in @md:h:bo:cb.

Apply a class from a viewport width up. Each breakpoint covers its width & every width above it.

Apply a class from a container's width up, not the viewport's. Mark the parent with ct:is first.

Apply a class when the device or the page matches a condition, or on the first frame an element renders.

Apply a class only while the element is in a state, such as hovered, focused or checked.

Style a part of the element rather than the element itself, such as its placeholder or the selected text.
