This tool lets you build a CSS pulse animation for buttons, icons, or badges without writing keyframes by hand. Pick from three presets — Heartbeat, Standard Pulse, or Glow Ripple — then tune the scale, speed, and easing function while watching a live preview, and copy the finished CSS in one click. Everything runs locally in your browser, with nothing sent to a server.
How to use
- Choose a preset: Heartbeat, Standard Pulse, or Glow Ripple.
- Adjust the Scale and Speed sliders to set how strong and how fast the animation pulses.
- Pick a Timing Function such as ease, linear, or cubic-bezier to shape the motion feel.
- Check the live preview, then click 'Copy CSS' to grab the generated @keyframes code.
FAQ
- Can I paste the generated CSS straight into my project?
- Yes — copy the @keyframes block and the .pulsing-element class, then apply that class to any element you want to animate.
- Why can't I adjust the scale for the Glow Ripple preset?
- The Glow Ripple preset is built around an expanding box-shadow rather than scaling, so only the Speed and Timing Function controls apply to it.
- How does the Heartbeat preset create a double-beat feel?
- It places different scale values at the 0%, 14%, 28%, 42%, 70%, and 100% marks, producing a quick small beat followed by a bigger one, like a real heartbeat.
