CMS helps to separate design of web site from its content. It means designer develops a web site and gives it to its owner or manager who can fill a certain design with different content. If necessary the content of web site, its images and graphics can be easily edited without intervention into design of web site. All changes become visible as soon as you make them. (Don‘t forget to reload page after making changes). Even if you are not an expert of HTML coding, you can easily manage the content of your web site yourself.
CMS has one more feature that is important to mention. It can be used like a basement for web templates. So, more and more web developers decide on CMS while creating their templates. Taking into consideration that Joomla is a comfortable, well-coded and easy-manageable CMS it was chosen to be the basement of Joomla Templates. These templates have been launched by the biggest and most reliably templates‘ provider Template Monster and they become very popular among those people who wish to build an outstanding web site.
