So, more and more sites are operating on Joomla nowadays. Joomla Templates are easy to use and they give you a chance to manage the content of your web site without going into details of the source code. A user friendly admin panel enables anyone to edit texts, pictures, product images, etc. If you wish to have Joomla like a splendid foundation for your online project, you can choose any example of Joomla Templates offered by Template Monster.
We might divide a page template into a header, content, sidebar and footer where these are in separate files. The content will change most between pages, so rather than having a content file, we include the content into a page file which pulls in the individual template files and defines the unique features of that page. The unique features of a page will be the title, description and article content. We can define these at the start of the page template with say PHP code to set the value of variables that are used by the other templates such as the header template. Then we assemble the page by including the required templates and inserting the content.
