css3 new selectors target on hover

Is there a way in css3 to target a div on hover, so if I have an sturucture like below could I target the divs as direct siblings of the h1?

<h1>item1</h1>
<div>this is the description for 1</div>

<h1>i开发者_运维百科tem2</h1>
<div>this is the description for 2</div>

<h1>item3</h1>
<div>this is the description for 3</div>

You can use the adjacent sibling combinator for this:

h1 + div:hover { ... }
