Through the use of a different template you can give your pages a completely new look. There are hundreds of templates available for CMSimple_XH, most of them are free (at least for private use).
Actually, there is no appearance of a website that you can't recreate with CMSimple_XH. And from the outer appearance it is not obvious if a site is operated with CMSimple_XH. Only a look into the source code shows it. Therefore we welcome a link to www.cmsimple-xh.org with the words "powered by CMSimple_XH" at the bottom of the website. However, this is not mandatory.
To give you an idea of what templates can do we installed the template switcher plugin, whose option list you see above the content area. Please have a try at it.
