Skeleton

A skeleton (.skeleton) is a placeholder block shown while real content is still loading — a shimmering or pulsing gray shape roughly the size and position of the text, image, or card it will be replaced by. It renders on any empty block-level element sized with inline width/height styles; the component itself only supplies the background animation and corner rounding, not any dimensions.
