Main Content
If you want to make a neat website, you wanna undertand the "main" class.
The "Main" class is where all the site's content will be, except for two elements: The headerpanel, and the navstrip. We'll get into those later though.
In your body tag, create a div with the class "main", and add some stuff to it. You'll see that the once fullscreen page, has been omitted to 4:3 standard. Wonderful!
This is where you'll add all your Layouts and Elements.
Fact!
Layouts are what is referred to here, like the main class. The main class is a layout!
