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).
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: revert-layer; column-rule: unset;
The column-rule
property is specified as one, two, or three of the values listed below, 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.
