Firefox 72: Individual CSS Transform Properties

New in Firefox 72 is the ability to individually define CSS Transform Properties. You can now separately define scale, rotate, and translate CSS properties, instead of having to chuff them all into one single transform property.

The translate, rotate, and scale properties allow authors to specify simple transforms independently, in a way that maps to typical user interface usage, rather than having to remember the order in transform that keeps the actions of transform(), rotate() and scale() independent and acting in screen coordinates.

element {
  scale: 2;
  rotate: 30deg;
  translate: -50% -50%;
}

The order that they are applied is, as per CSS Transforms Level 2 spec, first translate, then rotate, and then scale — not the order which you define them in.

By having individual transform props, this also means that we can animate and transition them separately.

@keyframes individual {
  50% {
    translate: 0 50%;
  }
  75% {
    scale: 1;
  }
}

element {
  transition:
    rotate 200ms ease-in-out,
    scale 500ms linear;
}

element:hover {
  scale: 2;
  rotate: -3deg;
}

Here’s a pen demonstrating its usage:

In Chrome these new props are still behind the #enable-experimental-web-platform-features feature flag.
