column-width

The column-width CSS property sets the ideal column width in a multi-column layout.

The column-width property specifies the preferred column width in a multi-column layout. The container will have as many columns as can fit without any of them having a width less than the column-width value. If the width of the container is narrower than the specified value, the single column’s width will be smaller than the declared column width.

This property can help you create responsive designs that fit different screen sizes. Especially in the presence of the column-count property (which has precedence), you must specify all related length values to achieve an exact column width. In horizontal text, these are width, column-width, column-gap, and column-rule-width.

Syntax example: column-width: auto;
