Designs for Content Management Systems
While this tutorial is focused on creating small static sites that are not stored directly inside a content management system (though they may certainly be uploaded to the same server and linked to from a CMS-generated page), there are many situations where using a CMS such as WordPress, Drupal, or Joomla will be convenient and appropriate. Most CMSs have an associated cottage industry of theme/template designers, who provide downloadable templates either for free or for a small fee.
If you're building a static site, you probably, don't want to use these designs, as they're full of template tags and programming logic specific to those systems. They will not work "out of the box" without being installed into the right CMS.
On the other hand, if you are using one of these CMS, these templates can save you a ton of time, as they include not just the HTML and CSS needed, but also the programming code needed to make sites fully functional (such as auto-generated navigation menus, category lists, author lists, calendars, and so forth).
