A template is the guide that describes where content should appear on a web page. Templates contain markers that describe where content from the database is added. Typical page objects are menus, logos, styling images and special links.
A template ensures that all pages within a site are consistent in their layout. Consistency improves the usability of a website. Visitors expect to see page content appear in the same place on every page.
A website template can be changed or a new one can be added, it's also possible to give some sections of the site a distinct look. Any changes to the template need to consider the brand of the organisation and retain some consistency across the website. Templates can usually only be added or edited by the site administrator or webmaster.
