# Align
|
|
|
|
The `align` style aligns children within a container.
|
|
|
|
## Syntax
|
|
|
|
--8<-- "docs/snippets/syntax_block_start.md"
|
|
align: <a href="../../css_types/horizontal"><horizontal></a> <a href="../../css_types/vertical"><vertical></a>;
|
|
|
|
align-horizontal: <a href="../../css_types/horizontal"><horizontal></a>;
|
|
align-vertical: <a href="../../css_types/vertical"><vertical></a>;
|
|
--8<-- "docs/snippets/syntax_block_end.md"
|
|
|
|
The `align` style takes a [`<horizontal>`](../../css_types/horizontal) followed by a [`<vertical>`](../../css_types/vertical).
|
|
|
|
You can also set the alignment for each axis individually with `align-horizontal` and `align-vertical`.
|
|
|
|
## Examples
|
|
|
|
### Basic usage
|
|
|
|
This example contains a simple app with two labels centered on the screen with `align: center middle;`:
|
|
|
|
=== "Output"
|
|
|
|
```{.textual path="docs/examples/styles/align.py"}
|
|
```
|
|
|
|
=== "align.py"
|
|
|
|
```python
|
|
--8<-- "docs/examples/styles/align.py"
|
|
```
|
|
|
|
=== "align.css"
|
|
|
|
```sass hl_lines="2"
|
|
--8<-- "docs/examples/styles/align.css"
|
|
```
|
|
|
|
### All alignments
|
|
|
|
The next example shows a 3 by 3 grid of containers with text labels.
|
|
Each label has been aligned differently inside its container, and its text shows its `align: ...` value.
|
|
|
|
=== "Output"
|
|
|
|
```{.textual path="docs/examples/styles/align_all.py"}
|
|
```
|
|
|
|
=== "align_all.py"
|
|
|
|
```python
|
|
--8<-- "docs/examples/styles/align_all.py"
|
|
```
|
|
|
|
=== "align_all.css"
|
|
|
|
```sass hl_lines="2 6 10 14 18 22 26 30 34"
|
|
--8<-- "docs/examples/styles/align_all.css"
|
|
```
|
|
|
|
## CSS
|
|
|
|
```sass
|
|
/* Align child widgets to the center. */
|
|
align: center middle;
|
|
/* Align child widget to the top right */
|
|
align: right top;
|
|
|
|
/* Change the horizontal alignment of the children of a widget */
|
|
align-horizontal: right;
|
|
/* Change the vertical alignment of the children of a widget */
|
|
align-vertical: middle;
|
|
```
|
|
|
|
## Python
|
|
```python
|
|
# Align child widgets to the center
|
|
widget.styles.align = ("center", "middle")
|
|
# Align child widgets to the top right
|
|
widget.styles.align = ("right", "top")
|
|
|
|
# Change the horizontal alignment of the children of a widget
|
|
widget.styles.align_horizontal = "right"
|
|
# Change the vertical alignment of the children of a widget
|
|
widget.styles.align_vertical = "middle"
|
|
```
|
|
