The foundation of your website presentation is controlled by a theme.  To access the themes screen, click on “Appearance” and “Theme” in the sub-menu.

When you open up the themes screen you will be presented with your current active theme on the top left.  From there on will be images of all themes you have installed on your system.  The base system comes with themes “Twenty Twelve”, “Twenty Thirteen”, and “Twenty Fourteen” as starter themes.  Many websites are built on of these themes.  This website is running on a theme called “Mantra” which I installed from WordPress.org (more on that later).
