CSS3 different custom easing for different properties

Question

I've set up an animation for a certain div.

.Animation
{
-webkit-animation-fill-mode: both; /*and also -moz, -ms etc. */
animation-fill-mode: both;
-webkit-animation-delay: 1s;
animation-delay: 1s;
-webkit-animation-duration: 2s;
animation-duration: 2s;
}

@-webkit-keyframes scaleAnimation /*and also -moz, -ms etc. */ 
{ 
0%
{
    opacity: 0;
    -webkit-transform: scale(2);
}

100%
{
    opacity: 1;
    -webkit-transform: scale(1);
}
}

.ScaleAnimation
{
-webkit-animation-name: scaleAnimation;  /*and also -moz, -ms etc. */
animation-name: scaleAnimation;
}

But i want a different custom ease (cubic bezier) for the opacity and another custom ease for the transform. How do I get this to work.

The following didn't work:

transition: opacity 1s ease-in-out;
transition: scale 1s ease-in-out;

So it definitely won't work with a custom ease, cubic-bezier(0.555, -0.130, 0.270, 1.075); for example.

Any thoughts? :)

Answer 1

For transitions, you could specify multiple transitions by comma-separating those.

transition: <duration> <property> <delay> <timing-function>, ....
transition: 1s opacity 1s ease-in-out, 1s scale 1s linear;

If you want to go the animation/keyframe route, then you could create two animation keyframes. One for scale, and the other for opacity. And then comma-separate them in the animation setup for the element.

The property for easing is animation-timing-function. For webkit based browsers (as it seems from your question that you don't mind vendor prefixes), it becomes -webkit-animation-timing-function.

You could set it up like this snippet:

div {
    width: 120px; height: 120px;
    background-color: red;
    display: inline-block;
}

div.d1 {
    -webkit-animation-fill-mode: both;
    -webkit-animation-delay: 2s, 2s;
    -webkit-animation-duration: 2s, 2s;
    -webkit-animation-name: scaleAnimation, opacityAnimation;
    -webkit-animation-timing-function: 
        cubic-bezier(0.1, 0.7, 1.0, 0.1),  ease-in;
}

div.d2 {
    -webkit-animation-fill-mode: both;
    -webkit-animation-delay: 2s, 2s;
    -webkit-animation-duration: 2s, 2s;
    -webkit-animation-name: scaleAnimation, opacityAnimation;
    -webkit-animation-timing-function: linear linear;
}

@-webkit-keyframes scaleAnimation { 
    0% {
        -webkit-transform: scale(2);
    }
    100% {
        -webkit-transform: scale(1);
    }
}

@-webkit-keyframes opacityAnimation { 
    0% {
        opacity: 0;
    }
    100% {
        opacity: 1;
    }
}

<div class="d1">D1</div>
<div class="d2">D2</div>
