How to use CSS Animation and Keyframe Generator
- Enter percentages and supported opacity or transform values for each step.
- Choose timing, delay, iteration and fill settings.
- Preview the motion, pause it when needed and export the CSS.
Example: CSS Animation and Keyframe Generator
Opacity 0 at 0% and opacity 1 at 100%, with a one-second duration.
Options
- Keyframe rows
- Each row names the percentage, opacity, translation, rotation and scale. Use the documented order and limits so the generated keyframes express the intended movement.
- Playback settings
- Duration, timing and playback options affect the controlled preview and exported declarations. They do not coordinate other elements on your site.

Review movement in its surrounding layout
A short preview can hide how motion interacts with real text, navigation or scrolling. Check the copied animation on the target element and preserve the reduced-motion alternative. Large transforms may move content outside its container; successful generation does not establish that the resulting motion is comfortable for every visitor.
Questions about CSS Animation and Keyframe Generator
Can I paste an arbitrary CSS declaration?
No. Use the supported property controls so the generator can validate every value.
Does the preview start animation in my website?
No. It runs only on the local sample. Integrate the exported CSS separately.
What happens when reduced motion is requested?
Retain the generated static alternative and test it with your page’s actual content.
