# Column-span

The `column-span` style specifies how many columns a widget will span in a grid layout.

!!! note

    This style only affects widgets that are direct children of a widget with `layout: grid`.

The style `column-span` accepts a single non-negative [`<integer>`](../../../css_types/integer) that quantifies how many columns the given widget spans.
