How to use
- Pick the preset you want: heartbeat, basic pulse, or glow ring.
- Use the Scale and Speed sliders to set how strong and how fast the animation runs.
- Choose a timing function — ease, linear, cubic-bezier, and more — to fine-tune the feel of the motion.
- Check the result in the preview, then use the "Copy CSS" button to grab the finished @keyframes code.
FAQ
- Can I use the generated CSS in my project as-is?
- Yes. Paste in the copied @keyframes and the .pulsing-element class, apply the class to your target element, and it works immediately.
- Why can't I adjust the scale on the glow ring effect?
- The glow ring (ripple) preset is built around an expanding box-shadow rather than a transform, so it exposes speed and timing function instead of scale.
- How does the heartbeat preset get that double-beat feel?
- It places different scale values at the 0%, 14%, 28%, 42%, 70%, and 100% marks, producing a keyframe pattern that beats once briefly and once bigger.
