Our system uses J QUERY UI to manage how the colors, fonts, buttons, and shading look within your pages. If you want to see how your site looks using any of the jquery themes you can enter the tag in your .wws template page like you see below. The name 'redmond' is a JQUERY theme name. The theme names can be seen on the jquery site. If a name has a space put a - in its place.
<%= IncludeStoreTheme(’catalogtheme’,’redmond’) %>
To permanently update your site's color theme, visit your store settings and click the design tab. You will see the fields for theme name with a drop down box.
