Style submenu items

Hi, I am using News 2 template, Joomla 3 and K2 2.6.9. I want to style a bit my menu. I want to change submenu items to be uppercase, but when i make the experiment and add text-transform: uppercase to the prospeties of .gkMenu > ul li div.childcontent a, than the background off the submenu items (the falling menus) is shorter and the last categories go out of the background. It doesn`t look good.
I would also like to add a small transparancy to the falling menu background and probably change its color. Would you please help me with that. My website is: http://www.zdravduh.com/

Hi

Here is a code You need to use:

Code: Select all

.gkMenu > ul li div.childcontent {
    height: auto !important;
    background: none repeat scroll 0 0 rgba(255, 255, 255, 0.8);
    text-transform: uppercase;
}


Thanks again
