# Max-width
|
|
|
|
The `max-width` rule sets a maximum width for a widget.
|
|
|
|
## Syntax
|
|
|
|
--8<-- "docs/snippets/syntax_block_start.md"
|
|
max-width: <a href="../../css_types/scalar"><scalar></a>;
|
|
--8<-- "docs/snippets/syntax_block_end.md"
|
|
|
|
The `max-width` rule accepts a [`<scalar>`](../../css_types/scalar) that defines an upper bound for the [`width`](./width) of a widget.
|
|
That is, the width of a widget is never allowed to exceed `max-width`.
|
|
|
|
### Values
|
|
|
|
--8<-- "docs/snippets/type_syntax/scalar.md"
|
|
|
|
## Example
|
|
|
|
The example below shows some placeholders that were defined to span horizontally from the top edge of the terminal to the bottom edge.
|
|
Then, we set `max-width` individually on each placeholder.
|
|
|
|
=== "Output"
|
|
|
|
```{.textual path="docs/examples/styles/max_width.py"}
|
|
```
|
|
|
|
=== "max_width.py"
|
|
|
|
```py
|
|
--8<-- "docs/examples/styles/max_width.py"
|
|
```
|
|
|
|
=== "max_width.css"
|
|
|
|
```scss
|
|
--8<-- "docs/examples/styles/max_width.css"
|
|
```
|
|
|
|
1. This won't affect the placeholder because its width is less than the maximum width.
|
|
|
|
## CSS
|
|
|
|
```sass
|
|
/* Set the maximum width to 10 rows */
|
|
max-width: 10;
|
|
|
|
/* Set the maximum width to 25% of the viewport width */
|
|
max-width: 25vh;
|
|
```
|
|
|
|
## Python
|
|
|
|
```python
|
|
# Set the maximum width to 10 rows
|
|
widget.styles.max_width = 10
|
|
|
|
# Set the maximum width to 25% of the viewport width
|
|
widget.styles.max_width = "25vh"
|
|
```
