Announcement bar

A bar that slides away when the page scrolls, and can be dismissed.

A gradient bar with a message and a link. It watches its own sample box or your page, slides away with a CSS transform so nothing jumps, and leaves a slim tab to bring it back. Dismissing it is kept in memory only: no cookie, no storage.

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 "Announcement bar" (announcement-bar): A bar that slides away when the page scrolls, and can be dismissed. 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.
