Not with out the Custom Design upgrade and modifications to the CSS, and due to the way Ocean Mist is designed, the outcome might not be too aesthetically pleasing.
I will say, that you need to consider making the labels for the menu tabs shorter. Shorter is always better, but it might be difficult given the titles that are there now.
Another option would be to go with a custom menu widget in the sidebar and then do away with the top menu altogether. You can get rid of the top menu by creating a blank custom menu and then assigning that menu to the “primary menu” location.
Thanks for the information! I will experiment with the custom menu widget. Would you know by chance how the folks at CNN make their webpages on WordPress so wide while mine appears to be so narrow on the screen?
