keyframes seem to fail

[matthewmueller]

@keyframes shake 
  0%
    transform: translateX(0);
  10%, 30%, 50%, 70%, 90% 
    transform: translateX(-10px)
  20%, 40%, 60%, 80% 
    transform: translateX(10px)

Should get transformed into:

@keyframes shake {
  0% {
    transform: translateX(0);
  }
  10%, 30%, 50%, 70%, 90% {
    transform: translateX(-10px);
  }
  20%, 40%, 60%, 80% {
    transform: translateX(10px);
  }
}
