The Limits Of CSS Animation

css / animation

Estimated reading time: 30 seconds

Before you start to experiment in moving elements with CSS it’s useful to know what can’t be animated. In the current spec, the following properties cannot be manipulated with keyframes or transitions:

  • gradients

  • scrolling of the entire body

  • almost anything to do with the background property, including background-image and background-position

(A list of what the CSS spec currently can animate.)

While there are usually ways around these limitations – animating absolutely positioned images placed with a z-index, for example, instead of background-images, or animating gradients – it’s good to know what CSS3 can’t do before you waste a lot of time and energy.
