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: unset;
