Easy fix for border problem?

Hello,
I seem to have a problem with the borders on my site.

http://tenimizer.com/user/

If you mouseover one of the links on the sidebar, you will notice that the right border which is white, is covering my top border. Is there a way to make the top border cover the right instead?

Thanks for the help, - Ryan Walters

P.S. - I know it doesn't look right for IE, I am in the beta stages of this site, and for me, IE will come after I design for FF.

 

not sure what you mean.... which border is the "right" and which "top" ?

 

I am not sure if the thing you are trying to do is possible. But I got an idea.
Why do not you try to make the sidebar blocks 1px wider and move them with 1 pixel to the right as I see it is a matter of 1 pixel only (you can use margin-right: -1px probably). Can use z-index to hide the blocks' right borders behind the main container. It is not the most professional approach but will make it look fine I think.

 

@DoOoM, thanks, but how would I go about doing this? It's a floating layout if that helps.
