What's a skeleton screen?

Gray placeholders showing where content will appear while loading. Better UX than a blank area or generic spinner — feels faster even if it isn't.

How is the shimmer achieved?

Animated gradient background sweeping across the element. CSS @keyframes with background-position shift.

Should I skip skeletons for fast loads?

Yes — under 200ms response, the skeleton's flash can feel jarring. Use skeletons for loads that reliably take 500ms+.

Can I generate for specific components?

Yes — card, list, table, paragraph, and custom shapes. Matches the layout of the final content so the transition feels seamless.

/* A skeleton should mirror the real layout: same block count, same rough sizes, same order. */
/* Mismatched skeletons read as a second layout shift rather than a loading hint. */

Fun Facts

Skeleton screens were popularized by Facebook's mobile app around 2014 — Luke Wroblewski coined the term and advocated for them as superior to traditional loading spinners.
A 2018 study by Bill Chung found that skeleton screens reduced perceived load time by up to 31% compared to blank screens and spinners in user perception tests.
LinkedIn, YouTube, and Slack all use skeleton screens — the shimmer effect creates an illusion of progress that reduces user anxiety during loading, leveraging the 'progress bar' psychological effect.
