IE 7 Hacks

Do anyone know a css hack that is exclusively for IE 7. Anyone help would be greatly appreciated.

Use conditional comments to provide alternative styles rather than css hacks.

Alright cheers salathe i'll see what i can find on google.

Thanks v.much daz, just what i was looking for. Also peoples views on conditional statements over hacks?

conditional statements are better cause they are supported. hacks, while do work, are work arounds. using conditional statements to get your IE7 looking right is better. although it being a seperate CSS file is a bit counter-intuitive for CSS, but it still works gooder.

Also, does anyone know of the code which i have to put in the wp header.php file to get the ie7 fix to work in wordpress.
