When should I use a CSS Animation Generator?
Use it when you want to add motion to buttons, cards, modals, alert boxes, or landing page sections. You can preview the motion and copy the @keyframes and animation properties right away.
Main parts of the animation property
- animation-name: the @keyframes name to run
- animation-duration: how long one animation cycle takes
- animation-timing-function: the acceleration curve of the motion
- animation-delay: the waiting time before the animation starts
- animation-iteration-count: how many times the animation repeats
- animation-direction: normal, reverse, or alternating playback
Recommended usage
- General card entrance effect: 0.5s to 0.9s
- Button hover highlight effect: 0.2s to 0.4s
- Modal entrance effect: 0.3s to 0.6s
- Infinite loops: use only for loading, highlight badges, or decorative elements
Performance tip
For better browser performance, it is usually better to animate transform and opacity instead of width, height, top, or left. This generator mainly creates transform and opacity based keyframes.
Is it okay to use many infinite loop animations?
Infinite animations can continuously draw attention and may affect performance. Use them only when the purpose is clear, such as loading states, highlight badges, or decorative elements.
How can I make a natural entrance animation?
Combining fade and slide is usually the most natural approach. A duration of 0.6s to 0.9s with ease-out or smooth cubic-bezier is recommended.
Why is prefers-reduced-motion necessary?
Some users are sensitive to motion effects. Adding prefers-reduced-motion support can reduce animations according to the user's accessibility settings.
