Template is the 'presentation layer' of a Joomla website. It usually consists of a file called index.php, which defines the general layout of all of the web pages, and a CSS (Cascading Style Sheet) file to define the formatting to use. You can apply different templates to different menu options if you want to create a different look and feel for certain pages. The template governs where the different module positions will be physically displayed on the screen, what fonts and colours the site will use.
