Apply CSS properties when transition ends - css

Question

How do I have the properties of a declaration apply to an element after the CSS3 transitions end? I have something like:
.something {
background: blue;
padding: 10px 0px;
background-clip: content-box;
transition: box-shadow 300ms;
}
.something:hover {
box-shadow: 0px 0px 3px blue;
padding: 0px;
margin: 10px 0px;
}
I'd like the padding and margin properties in the :hover declaration to be applied after the transition is done in 300ms.

Answer 1

you can add a delay like this:
transition: box-shadow 300ms, padding 300ms 400ms;
The box-shadow transition will start on hover and last 300ms, and the padding will start after 400ms and again last 300ms.
.something {
background: blue;
color: white;
padding: 0px;
background-clip: context-box;
transition: box-shadow 300ms, padding 300ms 400ms;
}
.something:hover {
box-shadow: 0px 0px 3px blue;
padding: 10px;
margin: 10px 0px;
}
<div class='something'>Something</div>

You can achieve this by placing another element inside or outside .something and applying padding and margin transitions to the new element, but with transition-delay value set to the time equal or greater than time of your initial box-shadow transition.
So, for instance:
<div class="immediate">
<div class="later">
I can haz transitions.
</div>
</div>
And CSS:
.immediate {
background: #eeb;
transition: box-shadow 300ms;
}
.immediate:hover {
box-shadow: 0 0 3px black;
}
.later {
margin: 0;
padding: 10px 0;
transition: all 400ms;
transition-delay: 300ms;
}
.later:hover {
margin: 10px 0;
padding: 0;
}
This will perform the box-shadow transition in 300ms, and afterwards margin and padding in 400ms (you can set this transition time to 0 if that's the effect you're looking for).

EDIT: Duncan Beattie's answer will do just fine, unless you need to perform different transitions on the same property. Otherwise there's no point to overcomplicate things with nested divs.

Answer 3

When using #Duncan Beattie´s solution one property will override the other.
This should work:
transition: box-shadow 300ms linear, padding 300ms linear 400ms;
Syntax:
transition: [property] [duration] [timing-function] [delay], ... more property-transitions
