The column-width
CSS property sets the ideal 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
/* Keyword value */ column-width: auto; /* <length> values */ column-width: 60px; column-width: 15.5em; column-width: 3.3vw; /* Global values */ column-width: inherit; column-width: initial; column-width: unset;
The column-width
property is specified as one of the values listed below.
Values
<length>
- Indicates the optimal column width. The actual column width may differ from the specified value: it may be wider when necessary to fill available space, and narrower when the available space is too small. The value must be strictly positive or the declaration is invalid. Percentage values are also invalid.
auto
- The width of the column is determined by other CSS properties, such as
column-count
.
