From Joomla! Documentation
To change the default Template for the Site (Front-end) or Administrator (Back-end), follow these steps:
Access the template manager
- Log in to the Administrator (Back-end). If you are not sure how to do this see: To log in to the Administrator (Back-end)
- Click on: Extensions → Template Manager
You will now see the Template Manager screen.
Note: If you do not see Template Manager listed as an option on the Extensions menu, then it is most likely because you are not logged in as a Super Administrator. Only Super Administrators will see this menu item.
Managing default template
From here you manage your templates for Front-end and Back-end. The default view shows your installed Front-end templates styles. The default style for the Front-end is marked with a star; in the image below it is protostar - Default.
To change the default style to beez3:
- click the checkbox left from the style name to select it;
- click "Default" on the toolbar;
the star changes from protostar to beez3 and you are done. Alternatively, you can click on the shadow of a template's default star to quickly set the template as default.
You can use the filter drop downs on the left or the filter search to limit the number of templates shown in the list of templates. Other options are:
- edit - edit the pages a template is shown on (see below)
- delete - delete a template (must not be default template)
- options - set options for templates
Assigning more than one template for the Front-end
Joomla! gives you the option of switching between two or more styles on the Front-end. This is done with "Menu Assignment", so you can set different styles for each menu or only a menu item. This allows specific "pages" that are defined by menu links to set for a "specific" style. Styles can be of different templates.
