You can create icon sprite animations using the steps() animation-timing function

button img {
  object-fit: cover;
  object-position: 0 0;
}
[aria-pressed="true"] img {
  animation: play 0.5s steps(20) forwards;
}
@keyframes play {
  to {
    object-position: 100% 0;
  }
}

Line clump

.line-clamp {
  display: -webkit-box;
  -webkit-line-clamp: 3;
  -webkit-box-orient: vertical;
  overflow: hidden;
}
