If we directly insert the content, we will create a new page template for each page of the site. But this is fine since we are not duplicating the header, footer and sidebar. To reduce the number of page templates, we can store our content in a database and use a page ID to identify which page content to insert. This ID is usually appended to our URLs of the website. If we do this, we are creating what is known as a Content Management System (CMS). Where the theme is likely to be changed often or people are encouraged to design new themes, a separate directory can be created to hold the various themes. A read me file could be included to credit the designer, or this information could be added to the start of the style sheet as a comment section.
CMS is friendly software used for managing the content of web design projects. You can also use CMS for keeping your documents and sharing them with your colleagues. For instance some information of your company is stored by means of CMS. So, each of your colleagues can add, change or update the content of your company‘s web site, its images and audio files. Here and now we see that CMS is acknowledged to be a necessary tool for managing web site content.
