column-rule

Summary

In multi-column layouts, the column-rule CSS property specifies a straight line, or "rule", to be drawn between each column. It is a convenient shorthand to avoid setting each of the individual column-rule-* properties separately : column-rule-width, column-rule-style and column-rule-color.

Syntax

column-rule: dotted;
column-rule: solid blue;
column-rule: solid 8px;
column-rule: thick inset blue;

/* Global values */
column-rule: inherit;
column-rule: initial;
column-rule: unset;

Values

Accepts one, two or three values in any order:

<'column-rule-width'>

Is a <length> or one of the three keywords, thin, medium, or thick. See border-width for details.

<'column-rule-style'>

See border-style for possible values and details.

<'column-rule-color'>

Is a <color> value.

Formal syntax

<'column-rule-width'> || <'column-rule-style'> || <'column-rule-color'>

Examples

/* same as "medium dotted currentColor" */
p.foo { column-rule: dotted; }

/* same as "medium solid blue" */
p.bar { column-rule: solid blue; }

/* same as "8px solid currentColor" */
