Frequently Asked Questions
What's the difference between animations and transitions?
Transitions animate between two states when triggered. Animations can have multiple keyframes, run automatically on load, loop infinitely, and control timing precisely.
How many keyframes should I use?
Use as few as needed for smooth motion. Start with 0% and 100%, add middle keyframes only where the motion needs to change direction or speed.
What properties animate best?
transform and opacity are GPU-accelerated and smoothest. Avoid animating width, height, margin, or other layout properties—they cause reflows.
