The column dimensions are determined by style sheet of the theme. Some themes apply a fixed
pixel width to the page layout, while others use percentages to make the page respond to the
width of the window or device.
Most desktop themes have a fixed width for the main column, and all activity takes place
within this enclosed area. Depending on your screen resolution, there is empty space on each
side of the main column.
1 Column Layout
The content area of a “1 Column” layout spans the full-width of the main column. This layout
is often used for a home page with a large banner or slider, or pages that require no navigation,
such as a login page, splash page, video, or full-page advertisement.
2 Columns with Left Bar
The content area of this layout is divided into two columns. The main content column floats to
the right, and the side bar floats to the left.
2 Columns with Right Bar
This layout is a mirror image of the other two-column layout. This time, the side bar floats to
the right, and the main content column floats to the left.
A 3-column layout has a main content area with two side columns. The left side bar and main
content column are wrapped together, and float as a unit to the left. The other side bar floats
to the right.
