Add new sections, each with one to four columns, to your layout. For instance, you might want a one-column section at the top, a two-column section in the middle, and then a one-column section at the bottom. To add a section, click <em>Add section</em> and click the desired number of columns. For multi-column sections, set the column width percentages and click <em>Add section</em> in the pop-up dialog.
