# Hatch

The `hatch` style fills a widget's background with a repeating character for a pleasing textured effect.

## Syntax

--8<-- "docs/snippets/syntax_block_start.md"
hatch: (<a href="../../css_types/hatch">&lt;hatch&gt;</a> | CHARACTER) <a href="../../css_types/color">&lt;color&gt;</a> [<a href="../../css_types/percentage">&lt;percentage&gt;</a>]
--8<-- "docs/snippets/syntax_block_end.md"

The hatch type can be specified with a constant, or a string. For example, `cross` for cross hatch, or `"T"` for a custom character.

The color can be any Textual color value.

An optional percentage can be used to set the opacity.
