CSS easing functions control the timing of animations, making them feel smoother and more natural. Here's a simple guide to selecting the right one:
Enter/exit animations: Use ease-out
to create a smooth deceleration as elements leave or appear on the screen.
Example: A modal fading out or a dropdown menu sliding into view.
Position changes: For elements already on the screen and moving between positions, choose ease-in-out
. It ensures smooth acceleration and deceleration.
Example: A card rearranging itself in a grid.
Constant animations (e.g., marquee): Use linear
for consistent, even motion without any variation in speed.
Example: marquee.
Hover effects: Most hover animations work well with ease
, creating subtle, natural transitions.
Example: A button slightly enlarging on hover.
Default to ease-out
for most cases. Avoid using ease-in
, as it can make animations feel abrupt and less polished.
This simple approach helps ensure your animations feel smooth and intuitive.
