[WSG] page break up

[Lori Cole]

Hi-I am new to CSS and strict.  The URL I am having trouble with is http://members.cox.net/loricole.newhome.html.  The style sheet is at http://members.cox.net.loricole/newtext.css. As you use the navigations tabs and go back to the home page, the blue background breaks up the white index card.  Refreshing the screen stops it unless you tab through and cursor back again.  I have IE v6. Also, I was intending for the hover of the tabs to be yellow but that does not happen.  Thank you for any help.  Lori
