CSS Animation property stays after animating

I'm trying to get a CSS animation property to stay after completing, is this possible?

This is what I'm trying to achieve...

The element should be hidden when the user lands on the page, after 3 seconds (or whatever), it should fade in and once the animation has completed it should stay there.

Here is a fiddle attempt...

Here is the code for preservation...

<h2>Test</h2>

<style>
@keyframes fadeIn {
0% {
opacity: 0;
}
100% {
opacity: 0.9;
}
}

h2 {
animation: fadeIn 1s ease-in-out 3s;
}
</style>


I know how to do this with jQuery.. it would be like this...

<h2>test</h2>

<script>
$(document).ready(function(){
$('h2').hide().delay(3000).fadeIn(3000)
});
</script>

Answer

I think you're looking for animation-fill-mode CSS3 property

https://developer.mozilla.org/en/CSS/animation-fill-mode

The animation-fill-mode CSS property specifies how a CSS animation should apply styles to its target before and after it is executing.

for your purpose just try to set

h2 {
  animation: fadeIn 1s ease-in-out 3s;
  animation-fill-mode: forwards;  
}

Setting forwards value «the target will retain the computed values set by the last keyframe encountered during execution»
