CSS Animation Generator — Create Beautiful Animations with Ease

Bring your web pages to life with smooth transitions and eye-catching effects, no manual CSS required. This tool keeps the workflow simple: set properties and preview on the left, supporting content below, and the sidebar on the left for popular and related tools.

No code needed

Pick your settings and generate clean, production-ready CSS without writing any by hand.

Live preview

Watch your animation play in real time so you can fine-tune it before copying the code.

Full control

Adjust duration, delay, iteration, easing, direction, fill mode, and your own keyframes.

Browser-based & free

Everything runs in your browser with no installs, sign-ups, or hidden fees.

How it works

  1. Set the animation name, duration, delay, and iteration count in the fields above.
  2. Choose a timing function, direction, and fill mode, then edit the keyframes if needed.
  3. Watch the live preview box update instantly to match your settings.
  4. Click Copy CSS to grab the code, or Reset to start over from the defaults.

Best practices

  • Keep durations short for subtle, professional motion.
  • Use ease or ease-in-out for natural-feeling movement.
  • Match the keyframe name to your animation-name value.
  • Preview the effect before copying the CSS.
  • Use infinite loops sparingly to avoid distraction.
  • Pair motion with a cohesive color scheme for impact.

Frequently asked questions

Do I need to know CSS to use this tool?

Not at all. Pick your animation settings, watch the live preview, and copy the ready-made CSS. You can paste it straight into your project without writing any code by hand.

Can I edit the keyframes myself?

Yes. The keyframes box is fully editable, so you can fine-tune the start, end, and any in-between steps to get exactly the motion you want.

Will these animations work in all browsers?

CSS animations are supported across all modern browsers and load quickly. The output uses standard properties, so your effects stay smooth and consistent.

What does the iteration count control?

It sets how many times the animation runs. Use a number like 1 or 3 for a fixed amount, or infinite to keep the animation looping for as long as the element is on screen.

How do timing function and direction differ?

The timing function shapes the speed curve, like ease or linear, while direction decides whether the animation plays forward, in reverse, or alternates back and forth.

Does this tool work on mobile devices?

Yes. The generator is responsive and runs in any modern browser, so you can build and preview animations on desktops, laptops, tablets, and phones.
