"Keyframes is a collection of tools to generate CSS properties.
The animation generator gives you a video-editor like timeline to create @keyframe animations and get the CSS output to use in your projects. There are also tools to create CSS Box shadows, convert colors, and find and copy CSS and HTML character codes.
Keyframes is completely built on Vue, and I used as few external resources as possible. It's hosted with Vercel, and uses localstorage to remember projects and user preferences instead of a database/backend. It's fully responsive, PWA-compatible, and supports native features like touch gestures and keyboard shortcuts."
