Full Customization
Fine-tune duration, delay, easing, direction, and iteration count.
Instant Code Generation
Get clean, copy-and-paste CSS code, including the `@keyframes` rule.
- Choose a Preset Animation: Select a starting point like "Fade In Up" or "Pulse" from the "Animation Type" dropdown. This loads the base `@keyframes`.
- Fine-Tune the Properties: Use the sliders and dropdowns in the "Controls" section to adjust the animation's behavior. Modify the duration, add a delay, or change the easing to create the exact effect you want.
- Preview Your Work: The "Preview" window on the left will automatically update to show your customized animation. Click "Replay Animation" to see it again.
- Copy the Generated CSS: Once you're happy with the result, go to the "Generated CSS" card and click the copy button. This copies the entire CSS snippet, including the `@keyframes` and the animation class.
- Implement in Your Project: Paste the copied code into your project's stylesheet. To apply the effect, add the class `your-element` to any HTML element you wish to animate. You can rename this class in the CSS to whatever you prefer.
