About CSS Animations
CSS animations allow elements to transition between styles over time using @keyframes rules and the animation shorthand property.
@keyframes define the animation steps. Each keyframe specifies CSS properties at a given percentage (0% = start, 100% = end).
Duration controls how long one cycle takes. Delay sets time before the animation starts.
Timing function controls acceleration: ease starts slow, speeds up, then slows; linear is constant speed.
Fill mode determines styles before/after animation: forwards keeps the final state, both applies in both directions.
Direction: alternate reverses every other cycle, creating smooth back-and-forth effects. Use with infinite iteration count for looping animations.
Performance tip: animate transform and opacity for best performance — they run on the GPU compositor and don't trigger layout recalculations.
What is a CSS slide animation?
A CSS slide animation moves an element from one position to another using the transform: translate() property inside a @keyframes rule. Unlike animating left/top, using transform is GPU-accelerated and does not trigger layout recalculations, making slide animations smooth even on lower-powered devices.
Common use cases
Slide animations are widely used for off-canvas navigation menus, carousel and slider transitions, notification toasts that enter from screen edges, and mobile app-style page transitions. They add a sense of direction and spatial context to UI interactions.
Frequently Asked Questions
Which CSS property should I use for slide animations?
Use transform: translateX() or translateY() inside @keyframes for best performance. Transform animations are composited on the GPU and avoid costly layout and paint operations that left/top animations cause.
How do I slide an element in from the right?
Set the starting keyframe to transform: translateX(100%) and the ending keyframe to transform: translateX(0). The element will slide in from the right edge of its container.
