The CSS column-span property describes how many columns an element spans across. It was introduced in CSS3 and only CSS3-compatible browsers support this property (like Firefox 4.0 and IE9).
Values
| Value | Description |
|---|---|
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. |
1 |
The element does not span multiple columns. |
CSS example:
body {
column-count:3;
}
h2 {
column-span:all;
background:silver;
}
