What is a CSS keyframe animation?

A CSS keyframe animation uses the @keyframes rule to define the intermediate steps of an animation sequence. You specify the styles at various points (0%, 50%, 100%, etc.), and the browser smoothly transitions between them. The animation property then applies the keyframe rule to an element, controlling duration, timing, and repetition.

What is the difference between CSS animations and transitions?

CSS transitions animate between two states (e.g., hover on/off) and require a trigger. CSS animations use @keyframes to define multiple steps and can run automatically, loop infinitely, and play in different directions. Animations are more powerful and flexible, while transitions are simpler for basic state changes.

What easing function should I use?

For most UI animations, 'ease-out' feels natural because elements decelerate as they reach their final position. 'Ease-in-out' works well for elements that start and end at rest. 'Linear' is best for constant-speed animations like spinning. The 'bouncy' cubic-bezier creates a playful overshoot effect.

Can I create custom animations beyond the presets?

Yes, the 'custom' preset lets you write your own @keyframes definitions directly in the editor. You can define any keyframe percentages and CSS properties you need. The tool then generates the complete animation code with your custom keyframes and the parameters you've configured.

How do I apply the generated animation to my HTML?

Copy the generated CSS code (both the @keyframes rule and the animation property) and paste it into your stylesheet. Apply the animation class to your HTML element. The @keyframes rule defines the animation steps, and the animation property controls how it plays.

Are CSS animations performant?

CSS animations that animate transform and opacity properties are GPU-accelerated and very performant. Avoid animating layout properties like width, height, margin, or padding, as these trigger layout recalculations. The presets in this tool primarily use transform and opacity for optimal performance.
