"Keyframes is a collection of simple tools for frontend development.
It includes a visual CSS @keyframe editor, a color palette creator with gradients, conversion, contrast, and color blindness, a CSS box-shadow generator and a special character search
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."
