Templates control the look and feel of your website.
This blog is installed with the Protostar template.
You can edit the options by clicking on the Working on Your Site, Template Settings link in the top menu (visible when you login).
For example you can change the site background color, highlights color, site title, site description and title font used.
More options are available in the site administrator. You may also install a new template using the extension manager.
