Some glossy theme users prefer to use graphics or text int heir sliders, and they don't want the text area on the right side of the slider with the "read more" button. If you'd like to do that instead as well, you'll need to use the css injector and add this bit of code:
The css injector is located in the "Public site area". You'll want to add a new rule. Use a title that you'll remember what this css code is for - something like "slider text" would work.
Set it so it only appears on the theme "glossy". Then save the rule, and refresh your site.
