HTML/CSS - vertical aligning a title.

I'm trying to have the title of my div to be dead centre vertically. e.g..

<div id="header">Title</div>

Title shows at the bottom of the div, how can i have it centered?

Hello forcerhpool,
The quick answer might be <div id="header"><h1>Title</h1></div> and #header h1 {line-height: 20px;}


Adjust that line-height as needed.
