Empty Anchor with Style

Hey guys

This may be really simple, but I’m stumped at the moment :confused:

Here’s a simplified version of what I’m trying to do:

<a style="display:block; height:400px; width:400px" href="#"></a>

I just want an empty area which acts as a link, but with the style embedded into the anchor tag. It works perfectly in FF but in IE, the ‘box’ is displayed but it’s not an actual working link.

Any ideas?
Cheers
