Is it possible to set different duration/delay for transform options?

Probably not directly, but the same effect can be achieved by nesting elements.

Yes you can do this directly with CSS3 animations. If you have an opacity transform from 0 to 1 that lasts 20 seconds, and a 90 degree rotation that lasts 10 seconds, then you create a keyframe at 10 seconds with opacity .5 and rotation 90 degrees and another keyframe at 20 seconds with opacity 1 and rotation 90 degrees. It's sort of a pain, but it will work. Nesting divs is a bit cleaner (as Doug says above)

Ok here's the code:

@-webkit-keyframes foo {
 0% {
    -webkit-transform: rotateX(0deg) rotateY(0deg) rotateZ(0deg);
    opacity: 0;
 }
 50% {
    -webkit-transform: rotateX(0deg) rotateY(0deg) rotateZ(0deg);
    opacity: 0.5;
 }

 100% {
    -webkit-transform: rotateX(0deg) rotateY(0deg) rotateZ(90deg);
    opacity: 1;
 }

And you'd put

-webkit-animation-duration: 20s;

into your HTML.

That would be problem to do it like Doug said if you have 3d perspective in your animation. Probably you could use "transform-style: preserve-3d" but it doesn't work in IE 10-11 and works weird in all other browsers exept Firefox. So the only solution i think is to use CSS3 animations. In your case it would be:

@-webkit-keyframes rotate_scale {

    0% {
        -webkit-transform: rotate(0deg) scale(0);
     }
     50% {
        -webkit-transform: rotate(90deg) scale(0);
     }
     100% {
        -webkit-transform: rotate(180deg) scale(2);
     }
}
@keyframes rotate_scale {

    0% {
        transform: rotate(0deg) scale(0);
     }
     50% {
        transform: rotate(90deg) scale(0);
     }
     100% {
        transform: rotate(180deg) scale(2);
     }
}

So you can set the longest duration of your transforms. For example 20 seconds for rotation: animation-duration: 20s; animation-name: rotate_scale; -webkit-animation-duration: 20s; -webkit-animation-name: rotate_scale; And then just calculate when your another transform will begin. In the examle scale begins in ten seconds after rotation. So it would be a half of full time ( 50% ). And it would last 10 seconds so till the end of full time ( 100% ). But if you'd like to make scale duration 5 seconds for example you'd need to add new keyframe 75% { transform: rotate(135deg) scale(2); } and write there two transforms.
