Animation Properties & Timing
Mastering CSS @keyframes, Timing Curves & Micro-Interactions
CSS Animation Shorthand & Property Syntax
The CSS animation property binds a @keyframes timeline to a selector with timing, duration, and loop parameters:
| Property | Example Value | Purpose |
|---|---|---|
| animation-name | pulse-glow | Matches the identifier declared in @keyframes name |
| animation-duration | 1.5s / 800ms | Total time required for one complete animation cycle |
| animation-timing-function | ease-in-out / cubic-bezier() | Mathematical acceleration curve of the motion |
| animation-iteration-count | infinite / 3 | Number of times the animation sequence repeats |
| animation-direction | alternate / normal | Plays forward then backward on each alternating iteration |
| animation-fill-mode | forwards / both | Retains the computed styles from the 100% keyframe at conclusion |
Performance Tips for 60fps Micro-Animations
For maximum battery efficiency and zero UI jank, stick to animating transform and opacity. Properties like width, height, top, or margin trigger CPU layout reflows on every tick, whereas transforms utilize the GPU compositor.
Combine your animations with our CSS transform generator, color grade with our CSS filter generator, or inspect web contrast in our contrast checker.
