The columns-start template and its child templates column and columns-end can be used to make a fixed number of columns (up to 5) that will span the entire page above a certain minimum width (100 ems for 5 columns, 80 for 4, 60 for 3 and 2). Below the minimum width, each column starting from the right will gracefully display below another one of the columns.
