FAQs
What is a CSS transition?
A CSS transition smoothly animates a property change over time — for example, a button that gently changes colour when hovered instead of snapping instantly.
What is the difference between a transition and an animation?
A transition animates between two states when something changes (like a hover), while a keyframe animation runs a scripted sequence on its own. Transitions are simpler and ideal for interactive effects.
Which timing function should I use?
ease gives a natural feel for most UI effects, linear moves at a constant speed, and ease-out works well for elements entering the screen.
Which properties animate most smoothly?
transform and opacity are the smoothest because browsers can animate them on the GPU. Animating layout properties like width causes more work and can look janky.
Is the transition property supported in all browsers?
Yes — CSS transitions are supported by all modern browsers, so the generated code works everywhere without prefixes.
