Animate Height with Grid

CSS can’t animate height: auto, but it can animate grid-template-rows from 0fr to 1fr.

.accordion {
  display: grid;
  grid-template-rows: 0fr;
  transition: grid-template-rows 0.3s;
}


.accordion > div {
  overflow: hidden;
}


.accordion.open {
  grid-template-rows: 1fr;
}
