Questions tagged [multiple-columns]

Multiple-columns are when text is split into a number of parallel text columns, rather than one column of text. For CSS Multicolumn layout, use the [css-multicolumn-layout] tag.

Multiple-columns are often found in newspapers and magazines, where a single column of text would create a line length longer than the ideal width of optimal readability.

Text can be set to use multiple-columns in CSS by using the CSS Multiple-column layout module.
