Fix website code examples (#1166)

The code examples in the comments were missing
indentation, e.g.

```
{
  marginTop: env(safe-area-inset-top)
}
```

would be rendered as

```
{
marginTop: env(safe-area-inset-top)
}
```

The trimming seems to be caused by
syntax-tree/mdast-util-mdx-jsx#15

Instead of waiting for an upstream fix this commit
refactors the examples to remove the indentation
and use CSS properties instead of JS objects.
