Most website design is controlled through one or more Cascading Style Sheet, or CSS, documents. The 1350 Grid system is no different; it is simply the precoded layout framework contained in its own CSS document.
The code is set up to allow for 15 columns, each with a width of 70 px and 10px margins on the left and right sides. These columns are assigned class names that are used to define the width and position of any containing box in the HTML, as seen in the sample of this page's code to the right.
Additional classes are set up and coded to allow for horizontal placement of the HTML containing boxes.
This all sounds confusing. To see a visual example of how the 1350 Grid System works, take look at this demo.
