Skeleton shimmer

A card skeleton that resolves into real content without shifting.

A skeleton with a shimmer that gives way to the content in the same box, so nothing on the page moves when it arrives. You choose how long the skeleton stays. With reduced motion the content is simply there.

Try it

<skeleton-shimmer>

Build one with your agent

Paste this into your agent. It asks you before it signs in, pays or goes further than checking and publishing.

Build me a Taggor component like "Skeleton shimmer" (skeleton-shimmer): A card skeleton that resolves into real content without shifting. Fetch https://taggor.dev/agent-setup/prompt.md and follow its instructions to set me up for Taggor. Ask me before you sign in, create an account, accept terms, pay for anything or type a secret. Check it with `taggor check` and publish it with `taggor publish`, and stop there. Do not promote it to production, attach it to a site, roll back anything or use --yes, --force or --force-drop-invalid unless I ask for exactly that in this conversation.
