Cover flow

A row of covers in depth, where the selected one faces front.

The selected cover faces front and the others turn toward it in depth, all in plain CSS with no canvas or WebGL. Click a side cover, use the arrow keys or the buttons. The covers are art drawn in code, with invented titles.

Try it

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 "Cover flow" (coverflow-3d): A row of covers in depth, where the selected one faces front. 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.
