One of the most advantageous aspects of content management systems is the ability to quickly create web sites with no programming or web design skills. In fact, there are plenty of webmasters that are building and operating dozens of web sites without any previous technical knowledge or web development experience. With content management systems like WordPress it has never been easier to design and manage multiple web sites.
Every day new themes and templates are created and shared online for free. These templates are actually entire site designs that can be applied to a site with a click of the mouse. One of the interesting features of every content management system is their ability to change the design of an entire web site without affecting the content of the pages and posts. You can even test out new designs and create your own custom themes without having to worry about losing data or disrupting the site's content in any way.
