Banner Ads Don't Fit

[pkwjr]

When I place a banner ad in my sight, either the top or bottom of the ad is cut off by maybe one line. You can actually scroll through it to adjust it just right, but I am sure visitors don't do that.
The rectangle or skyscraper ads are fine.
Is there an type of code adjustment I can make to fix this annoying issue?
Thanks

Try placing the ad in div tags with the proper height specified, something like <div style="height:90px;">your ad code</div>. If it still scrolls, nudge the height up a pixel or two.

Also, make sure no other HTML/CSS formatting is limiting your ad's available space.
