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.
Try it
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).
