CSS column-rule-style Property

The column-rule-style specifies the style of the rule between columns. A column-rule is similar to a border that you can add to separate adjacent columns. It can also have styles like a border.

This property is one of the CSS3 properties.

One should define the columns or columns-count properties, because there should be columns in order to specify the style for it.

The column-rule-style property has the following values:

  • none
  • hidden
  • dotted
  • dashed
  • solid
  • double
  • groove
  • ridge
  • inset
  • outset

Some property extensions are added, such as -webkit- for Safari, Google Chrome, and Opera (newer versions), -moz- for Firefox, -o- for older versions of Opera, etc.
Initial Value none
Applies to Multicol elements.
Inherited No.
Animatable No.
Version CSS3

It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
