column-rule

The column-rule shorthand CSS property sets the width, style, and color of the line drawn between columns in a multi-column layout.

It is a shorthand property that sets the individual column-rule-* properties in a single, convenient declaration: column-rule-width, column-rule-style, and column-rule-color.

Note: As with all shorthand properties, any individual value that is not specified is set to its corresponding initial value (possibly overriding values previously set using non-shorthand properties).

Syntax

column-rule: dotted; column-rule: solid 8px; column-rule: solid blue; column-rule: thick inset blue;  /* Global values */ column-rule: inherit; column-rule: initial; column-rule: revert; column-rule: unset; 

The column-rule property is specified as one, two, or three of the values listed below, in any order.
