What's Wrong With "Eclipse"?

So I Was Making My Website and i decided to download "Eclipse" IDE, i use "Visual Studio Code" or "Atom", i downloaded "Eclipse" because why not but there was a problem while i was designing CSS.

.move {
  animation-name: move;
  animation-iteration-count: infinite;
  animation-duration: 10s;
  position: relative;
  top: 10px;
  left: 10px;
  width: 20px;
  height: 20px;
}

.submove {
  animation-name: submove;
  animation-iteration-count: infinite;
  animation-duration: 10s;
  position: relative;
  top: 15px;
  left: 10px;
  width: 10px;
  height: 20px;
}

Eclipse had a problem with .submove. i wrote .move in VSC (Visual Studio Code), after the animation-name: submove; it started saying things like "colon expected" at the part mation-iteration-, (i mean the part mation-iteration- of animation-iteration-count) i don't know what the difference is that Eclipse pointing out, how do i fix this?
