I'm trying to get rid of the border on my navigation block and in the style.css I can style the border but I can't get rid of it.

If I style it #block-user-1 .content { border: solid 1px #ddd } it changes it to the style but if I style it like #block-user-1 { border: none } the thin border remains.

I have no idea why its doing this. I even tried styling it to match the white background of my container and that didn't work either.

Help!
