The column-rule
CSS property sets the width, style, and color of the rule (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: unset;
The column-rule
property is specified as one, two, or three of the values listed below, in any order.
<'column-rule-width'>
<length>
or one of the three keywords, thin
, medium
, or thick
. See border-width
for details.<'column-rule-style'>
border-style
for possible values and details.<'column-rule-color'>
<color>
value.<'column-rule-width'> || <'column-rule-style'> || <'column-rule-color'>
/* 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" */ p.baz { column-rule: solid 8px; } p.abc { column-rule: thick inset blue; }
<p class="content-box"> This is a bunch of text split into three columns. Take note of how the `column-rule` property is used to adjust the style, width, and color of the rule that appears between the columns. </p>
.content-box { padding: 0.3em; background: #ff7; column-count: 3; column-rule: inset 2px #33f; }
