# Align
The `align` style aligns children within a container.
Not to be confused with [`content-align`](../content_align).
You can specify the alignment of children on both the horizontal and vertical axes at the same time,
or on each of the axis separately.
## Syntax
```
align: <HORIZONTAL> <VERTICAL>;
align-horizontal: <HORIZONTAL>;
align-vertical: <VERTICAL>;
```
### Values
#### `HORIZONTAL`
| Value | Description |
| ---------------- | -------------------------------------------------- |
| `left` (default) | Align content on the left of the horizontal axis |
| `center` | Align content in the center of the horizontal axis |
| `right` | Align content on the right of the horizontal axis |
#### `VERTICAL`
| Value | Description |
| --------------- | ------------------------------------------------ |
| `top` (default) | Align content at the top of the vertical axis |
| `middle` | Align content in the middle of the vertical axis |
| `bottom` | Align content at the bottom of the vertical axis |
## Examples
This example contains a simple app with two labels centered on the screen with `align: center middle;`:
=== "align.py"
```python
--8<-- "docs/examples/styles/align.py"
```
=== "align.css"
```scss hl_lines="2"
--8<-- "docs/examples/styles/align.css"
```
=== "Output"
```{.textual path="docs/examples/styles/align.py"}
```
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.
=== "align_all.py"
```python
--8<-- "docs/examples/styles/align_all.py"
```
=== "align_all.css"
```css
--8<-- "docs/examples/styles/align_all.css"
```
=== "Output"
```{.textual path="docs/examples/styles/align_all.py"}
```
## CSS
```sass
/* Align child widgets to the center. */
align: center middle;
/* Align child widget to th top right */
align: right top;
```
## 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")
```
