Joomla is one of the most popular Content Management Systems (CMS) out there. A CMS allows you to update and modify a web page without understanding its actual code, which makes them a major advantage to someone who wants to regularly update their website without learning a complicated system of coding.
Joomla also features commercial and non-commercial unlimited plugin support, and has no limitations in meeting any layout requirement. This means it’s highly customizable, allowing you to create essentially any type of webpage you want in Joomla while still using their easy, handy system. Find out more at : http://www.joomla.org/
