Free copy-paste CSS transitions for common UI patterns — modals, dropdowns, card resizes, text swaps.
About Transitions.dev
transitions.dev is a free curated library of CSS transitions for common web app UI patterns. Each example covers a real interaction — opening a modal, animating a dropdown, resizing a card on hover, swapping out text — and ships with copy-paste ready code that drops into any project. No build step, no framework lock-in, no dependencies.
Whether you're prototyping in vanilla HTML/CSS or adding polish to a Next.js app, the snippets work as-is. Built by developers who got tired of rewriting the same animations from scratch.
