If you can do it in html, you can do it in Xoops. Simply put. All the theme is, is an html file that has smarty code in it, to pull the info from the php scripts. Of course you have the css style sheet that controls your colors, fonts and any special class' that you might have. Building a theme was a concept that I, for the longest time, was intimidated by. Its not too difficult, just takes time and experimentation.
This theme was purchased off of templatemonster.com.
Thanks for the comp on the theme though.
