To center a widget within a container use
[`align`](https://textual.textualize.io/styles/align/). But remember that
`align` works on the *children* of a container, it isn't something you use
on the child you want centered.

For example, here's an app that shows a `Button` in the middle of a
`Screen`:

```python
from textual.app import App, ComposeResult
from textual.widgets import Button

class ButtonApp(App):

    CSS = """
    Screen {
        align: center middle;
    }
    """

    def compose(self) -> ComposeResult:
        yield Button("PUSH ME!")

if __name__ == "__main__":
    ButtonApp().run()
```
