Utilities

Helpers that aren't components. Covers class merging, DOM reparenting, and scroll and text effects.

The utilities are the parts of Spark UI that don't render a component: a class merger, a DOM escape hatch, and two presentation effects. They use the same tokens and conventions as the rest of Spark UI.

Merge Tailwind class strings, with later conflicting classes winning.

Reparent

Move rendered content elsewhere in the DOM without unmounting it.

Scroll Fade

Fade the edges of a scrollable container to hint at overflow.

Shimmer

Animate a highlight across text, for loading and streaming states.
