Individual CSS Transform Functions

Go to Source

Dan Wilson documents a classic annoyance with transforms:

button {
  transform: translateY(-150%);
}
button:hover {
  /* will (perhaps unintentionally) override the original translate */
  transform: scale(.8);
}

The native (and WET) solution is list the original transform again:

button:hover {
  transform: translateY(-150%) scale(.8);
}

Dan’s trick is to use custom properties instead. Set them all on the element right up front, then re-set them the :hover state:

:root {
  --tx: 150%;
  --scale: 1;
}
button {
  transform: 
    translateY(var(--tx))
    scale(var(--scale));
}
button:hover {
  --scale: 0.8;
}

Cascading custom properties FTW.
