ℹ️ About this tool
Free Online CSS Animation Builder
QuickTools CSS Animation Builder lets you create stunning CSS animations visually without writing a single keyframe by hand. Choose from dozens of categorized presets — entrances, exits, attention seekers, and loops — or craft your own custom keyframes. Fine-tune duration, delay, timing function, iteration count, direction, and fill mode with intuitive controls, then preview the result in real time on a live element. When you are satisfied, copy the clean, production-ready CSS with one click. Perfect for web designers, front-end developers, and anyone who wants polished animations without the complexity of manual keyframe coding.
How to Use CSS Animation Builder
Browse the preset categories — Entrances, Exits, Attention Seekers, or Loops — and click one to apply it. Adjust the animation properties using the controls: set the duration and delay in seconds, pick a timing function, choose how many times it repeats, set the direction, and select a fill mode. Preview the animation live, then click Copy CSS to grab the production-ready code for your project.

Frequently Asked Questions
What types of animations can I create?
You can create entrance animations, exit animations, attention seekers, and looping animations. Choose from pre-built presets or write your own custom keyframes to achieve any effect you need.
Can I use the generated code in production?
Absolutely. The generated CSS is clean, standards-compliant, and ready for production use. Simply copy the code and paste it into your stylesheet or component file.
Do I need to add vendor prefixes?
Modern browsers have excellent support for CSS animations without vendor prefixes. However, if you need to support very old browsers, you can run the output through an autoprefixer tool for full compatibility.
Can I write my own custom keyframes?
Yes. Switch to the Custom Keyframes tab and write your own @keyframes rules. The builder will apply your custom animation to the preview element so you can see the result immediately.
Does the tool work offline?
Once the page has loaded, the tool runs entirely in your browser with no server communication. You can use it offline as long as the page is cached, making it ideal for use during travel or on limited connections.
