CSS animation templates with the motion already written. Every one uses CSS keyframes for fades, reveals, marquees, and looping backgrounds, in plain CSS with no animation library to install. Paste one into Claude Code, Replit, Lovable, ChatGPT Codex, Bolt, or Cursor and the motion arrives with the design.
A section where the motion is written in CSS keyframes and ships with the markup. You paste the HTML and CSS together and the animation runs, with no JavaScript library to add.
No. The motion is plain CSS, so there is nothing to install and nothing to configure. That keeps the page light and makes it simple for an AI coding tool to edit.
Yes. Ask your AI coding tool to slow down or speed up the motion and it edits the keyframe timing directly. Describe the feeling you want and it will adjust the duration and easing.
Handled well it stays light, since CSS animation runs on the browser's own compositor. Test on a phone before you ship, since that is where most traffic lands.
