Summary
The column-width
CSS property suggests an optimal column width. The column-width is the maximum width a column will become before adding another column. For instance, a 300px column width a gap of 0px would be a single column at 599px, but at 600px it would be split into 2 columns. This allows us to achieve scalable designs that fit different screen sizes. Especially in presence of the column-count
CSS property which has precedence, to set an exact column width, all length values must be specified. In horizontal text these are width
, column-width
, column-gap
, and column-rule-width
.

Syntax
/* Keyword value */ column-width: auto; /* Different <length> values */ column-width: 6px; column-width: 25em; column-width: 0.3vw; /* Global values */ column-width: inherit; column-width: initial; column-width: unset;
Values
<length>
- Is a
<length>
value giving a hint of the optimal width of the column. The actual column width may be wider (to fill the available space), or narrower (only if the available space is smaller than the specified column width). The length must be strictly positive or the declaration is invalid. auto
- Is a keyword indicating that the width of the column should be determined by other CSS properties, like
column-count
.
Formal syntax
<length> | auto
