Maintaining the final state at end of a CSS3 animation

Question

I\'m running an animation on some elements that are set to opacity: 0; in the CSS. The animation class is applied onClick, and, using keyframes, it changes the

Answer 1

Use animation-fill-mode: forwards;

animation-fill-mode: forwards;

The element will retain the style values that is set by the last keyframe (depends on animation-direction and animation-iteration-count).

Note: The @keyframes rule is not supported in Internet Explorer 9 and earlier versions.

Working example

div {
  width: 100px;
  height: 100px;
  background: red;
  position :relative;
  -webkit-animation: mymove 3ss forwards; /* Safari 4.0 - 8.0 */
  animation: bubble 3s forwards;
  /* animation-name: bubble; 
  animation-duration: 3s;
  animation-fill-mode: forwards; */
}

/* Safari */
@-webkit-keyframes bubble  {
  0%   { transform:scale(0.5); opacity:0.0; left:0}
    50%  { transform:scale(1.2); opacity:0.5; left:100px}
    100% { transform:scale(1.0); opacity:1.0; left:200px}
}

/* Standard syntax */
@keyframes bubble  {
   0%   { transform:scale(0.5); opacity:0.0; left:0}
    50%  { transform:scale(1.2); opacity:0.5; left:100px}
    100% { transform:scale(1.0); opacity:1.0; left:200px}
}

<h1>The keyframes </h1>
<div></div>

Answer 2

If you are using more animation attributes the shorthand is:

animation: bubble 2s linear 0.5s 1 normal forwards;

This gives:

• 2s duration
• linear timing-function
• 0.5s delay
• 1 iteration-count (can be 'infinite')
• normal direction
• forwards fill-mode (set 'backwards' if you want to have compatibility to use the end position as the final state[this is to support browsers that has animations turned off]{and to answer only the title, and not your specific case})

Answer 3

Try adding animation-fill-mode: forwards;. For example like this:

-webkit-animation: bubble 1.0s forwards; /* for less modern browsers */
        animation: bubble 1.0s forwards;

Answer 4

IF NOT USING THE SHORT HAND VERSION: Make sure the animation-fill-mode: forwards is AFTER the animation declaration or it will not work...

animation-fill-mode: forwards;
animation-name: appear;
animation-duration: 1s;
animation-delay: 1s;

vs

animation-name: appear;
animation-duration: 1s;
animation-fill-mode: forwards;
animation-delay: 1s;
