How to remove the little space between h1 & inner a

With markup like

http://jsfiddle.net/rUsbJ/

<h1><a href="#">Header with link</a></h1>
<h1>Header without link</h1>

As you can see theres some space between the <a> and the parent <h1>. How can I remove it?

Set the anchor to display:inline-block or just display:block

(anchors are by default inline-level)

Although in my browser (Chrome 9), both H1 elements have the same height: http://jsfiddle.net/rUsbJ/1/
