Background

The background rule sets the background color of the widget.

Syntax

background: <COLOR> [<PERCENTAGE>];

Example

This example creates three widgets and applies a different background to each.

=== "background.py"

```python
--8<-- "docs/examples/styles/background.py"
```

=== "background.css"

```sass
--8<-- "docs/examples/styles/background.css"
```

=== "Output"

```{.textual path="docs/examples/styles/background.py"}
```

CSS

/* Blue background */
background: blue;

/* 20% red backround */
background: red 20%;

/* RGB color */
background: rgb(100,120,200);

Python

You can use the same syntax as CSS, or explicitly set a Color object for finer-grained control.

# Set blue background
widget.styles.background = "blue"

from textual.color import Color
# Set with a color object
widget.styles.background = Color.parse("pink")
widget.styles.background = Color(120, 60, 100)
