About CSS Animations

CSS animations create smooth, performant animations using keyframes:

  • Define keyframe percentages (0%, 50%, 100%)
  • Control transform, opacity, and other properties
  • Set duration, delay, iteration count, and easing
  • GPU-accelerated for smooth performance

💡 Tip: Use transform and opacity for best performance. Avoid animating layout properties like width/height.

What It Does

A CSS Animation Generator creates smooth, performant CSS keyframe animations with visual controls. This tool allows you to define multiple keyframes at different percentages (0%, 50%, 100%, etc.) and control properties like transform (translate, rotate, scale), opacity, and more. The generator provides a timeline-based interface for managing keyframes, with controls for animation duration, delay, iteration count, direction, easing functions, and fill modes. A live preview shows the animation in action, helping you perfect the timing and effects before copying the code. The tool generates both @keyframes rules and animation property CSS, making it easy to create professional animations without writing complex CSS manually. Perfect for creating loading animations, hover effects, transitions, and interactive UI elements.

Key Features:

  • Visual keyframe timeline editor
  • Multiple keyframe points (0%, 50%, 100%, custom)
  • Transform controls: translate, rotate, scale
  • Opacity and color animation support
  • Animation timing controls: duration, delay, iteration
  • Easing function selector (ease, linear, cubic-bezier)
  • Animation direction and fill mode options
  • Live preview of animation
  • Copy keyframes and animation CSS separately or together

How To Use

Creating CSS animations is straightforward. Define keyframes, set animation properties, and preview the result.

1

Set Animation Properties

Configure the animation name, duration, delay, iteration count, direction, easing function, and fill mode. These control how the animation behaves.

2

Add Keyframes

Add keyframe points at different percentages (0%, 50%, 100%). Each keyframe defines the element's state at that point in the animation.

3

Configure Keyframe Properties

For each keyframe, set transform values (translate X/Y, rotate, scale X/Y) and opacity. The preview updates in real-time as you adjust values.

4

Preview and Copy

Watch the live preview to see your animation. When satisfied, copy the @keyframes rule, animation property, or both together.

Pro Tips

  • •Use transform and opacity for best performance (GPU accelerated)
  • •Avoid animating layout properties (width, height, margin)
  • •Start with 3 keyframes (0%, 50%, 100%) for simple animations
  • •Use easing functions to create natural motion
  • •Test animation performance on target devices

Frequently Asked Questions

1 Why use CSS animations instead of JavaScript?
CSS animations are GPU-accelerated, more performant, and don't require JavaScript. They run on a separate thread, keeping the main thread free. CSS animations are also easier to pause, reverse, and control with media queries. However, JavaScript offers more complex logic and interactivity.
2 Can I animate any CSS property?
Technically yes, but for performance, stick to transform and opacity. Animating layout properties (width, height, margin, padding) triggers expensive reflows. Animating colors is possible but less performant than transform/opacity.
3 What's the difference between animation and transition?
Transitions animate between two states (hover, focus). Animations use keyframes to create complex, multi-step animations that can loop, reverse, and have more control. Use transitions for simple state changes, animations for complex sequences.
