# 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`.
## Syntax
--8<-- "docs/snippets/syntax_block_start.md"
column-span: <a href="../../../css_types/integer"><integer></a>;
--8<-- "docs/snippets/syntax_block_end.md"
The `column-span` style accepts a single non-negative [`<integer>`](../../css_types/integer.md) that quantifies how many columns the given widget spans.
## Example
The example below shows a 4 by 4 grid where many placeholders span over several columns.
=== "Output"
```{.textual path="docs/examples/styles/column_span.py"}
```
=== "column_span.py"
```py
--8<-- "docs/examples/styles/column_span.py"
```
=== "column_span.tcss"
```css hl_lines="2 5 8 11 14 20"
--8<-- "docs/examples/styles/column_span.tcss"
```
## CSS
```css
column-span: 3;
```
## Python
```py
widget.styles.column_span = 3
```
