Constituent properties

This property is a shorthand for the following CSS properties:

• column-count
• column-width

Syntax

/* Column width */
columns: 18em;

columns: 2;

/* Both column width and count */
columns: 2 auto;
columns: auto 12em;
columns: auto auto;

/* Global values */

columns: unset;

The columns property may be specified as one or two of the values listed below, in any order.

The ideal column width, defined as a <length> or the keyword auto. The actual width may be wider or narrower to fit the available space. See column-width.

<'column-count'>

The ideal number of columns into which the element's content should be flowed, defined as an <integer> or the keyword auto. If neither this value nor the column's width are auto, it merely indicates the maximum allowable number of columns. See column-count.
