The following steps always produce either a single-column layout or a multicolumn layout with equal-width columns.

Select the text frame whose margins you want to change by Control-clicking the frame.
Choose
.Do the following:
To change the margins, specify the new size and position in the Unrotated Size and Offset From areas. The Offset From Top and Offset From Left options specify the top and left margins. The bottom and right margins are then determined by the text frame’s width and height.
To change the number of columns or the gap between columns, change the values in the Columns area.
Click Set.
