Padding Issue in IE7

Y'day I faced one issue in IE7 browser while working on our one of the latest and big sites navigation menu.
IE7 doubles the top padding on my navigation menu.

My Css code :

 

.nav {
 clear:left;
 padding: 16px 0 0 30px;
 }

After playing with this and googling we fixed the issue.
Here is the fix....
Just add the display:inline-block to the div double padding. That's it....

 

.nav {
 clear:left;
 display:inline-block;
 padding: 16px 0 0 30px;
 }
