We want the Zone names to appear inside a green bar with rounded ends, to match the other elements of our site (still in development).

Designer's example:
http://www.greenbeam.com/gb_redesign/GBP_design.htm

Current development:
http://ijoomla.m29.com/index.php?option=com_news_portal&Itemid=38

I am only marginally adept at programming, but I have located the CSS code that the current developer has used to achieve the current green bars, if that would help.
