Stopping a CSS3 Animation on last frame

I have a 4 part CSS3 animation playing on click - but the last part of the animation is meant to take it off the screen.

However, it always goes back to its original state once it has played. Anyone know how I can stop it on its last css frame (100%), or else how to get rid of the whole div it is in once it has played.

@keyframes colorchange {
  0%   { transform: scale(1.0) rotate(0deg); }
  50%  { transform: rotate(340deg) translate(-300px,0px) }
  100% { transform: scale(0.5) rotate(5deg) translate(1140px,-137px); }
}

You're looking for:

animation-fill-mode: forwards;

More info on MDN and browser support list on canIuse.

If you want to add this behaviour to a shorthand animation property definition, the order of sub-properties is as follows

animation-name - default none

animation-duration - default 0s

animation-timing-function - default ease

animation-delay - default 0s

animation-iteration-count - default 1

animation-direction - default normal

animation-fill-mode - you need to set this to forwards

animation-play-state - default running

Therefore in the most common case, the result will be something like this

animation: colorchange 1s ease 0s 1 normal forwards;

See the MDN documentation here

-webkit-animation-fill-mode: forwards; /* Safari 4.0 - 8.0 */
animation-fill-mode: forwards;

Browser Support

• Chrome 43.0 (4.0 -webkit-)
• IE 10.0
• Mozilla 16.0 ( 5.0 -moz-)
• Shafari 4.0 -webkit-
• Opera 15.0 -webkit- (12.112.0 -o-)

Usage:-

.fadeIn {
  animation-name: fadeIn;
    -webkit-animation-name: fadeIn;

    animation-duration: 1.5s;
    -webkit-animation-duration: 1.5s;

    animation-timing-function: ease;
    -webkit-animation-timing-function: ease;

     animation-fill-mode: forwards;
    -webkit-animation-fill-mode: forwards;
}


@keyframes fadeIn {
  from {
    opacity: 0;
  }

  to {
    opacity: 1;
  }
}

@-webkit-keyframes fadeIn {
  from {
    opacity: 0;
  }

  to {
    opacity: 1;
  }
}

The best way seems to put the final state at the main part of css. Like here, i put width to 220px, so that it finally becomes 220px. But starting to 0px;

div.menu-item1 {
  font-size: 20px;
  border: 2px solid #fff;
  width: 220px;
  animation: slide 1s;
  -webkit-animation: slide 1s; /* Safari and Chrome */
}
@-webkit-keyframes slide { /* Safari and Chrome */
  from {width:0px;}
  to {width:220px;}
}
