How CSS transitions work

The transition shorthand animates a property smoothly when its value changes — on hover, focus, or a class toggle. It takes the property to watch, a duration, a timing function (the easing curve), and an optional delay. Transitioning transform and opacity is cheapest because the browser can offload them to the GPU. Hover the box above to feel your settings, then copy the code.
