The column-span CSS property makes it possible for an element to span across all columns when its value is set to all.

/* Keyword values */
column-span: none;
column-span: all;

/* Global values */
column-span: inherit;
column-span: initial;
column-span: unset;

An element that spans more than one column is called a spanning element.

Syntax

The column-span property is specified as one of the keyword values listed below.

Values

none
The element does not span multiple columns.
all
The element spans across all columns. Content in the normal flow that appears before the element is automatically balanced across all columns before the element appears. The element establishes a new block formatting context.

Formal syntax

none | all

Example

In this example, the heading is made to span across all the columns of the article.

HTML

<article>
  <h2>Header spanning all of the columns</h2>
  <p>
     The h2 should span all the columns. The rest 
     of the text should be distributed among the columns.
  </p>
  <p>This is a bunch of text split into three columns using the CSS `columns` property. The text is equally distributed over the columns.</p>
  <p>This is a bunch of text split into three columns using the CSS `columns` property. The text is equally distributed over the columns.</p>
