This is an example of the very minimal that needs to be in a CMSMS template. No stylesheet is attached to the template, which is why it doesn't look very nice...
However, to make it slightly more appealing, some inline styling was used, for floating the content to the right of the menu.
The menu in this page template is using the Minimal Navigation template for Menu Manager. No accessibility stuff is in there, so it's recommended that the Simple Navigation menu template is rather used.
