## Notes on CSS vars
Currently using `:root` selectors won't work due to template styles prepending `.mw-parser-output`.
One possible fix is to wrap the entire content into a `div` element and adding the declarations to this, e.g.
```css
div#content-wrap {
--padding: 10px
}
.content {
padding: var( --padding )
}
```
Wikitext
```html
<div id="content-wrap">
<div class=".content">
The WikiText...
</div>
</div>
```
