Note CSS VarsEdit

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.

div#content-wrap {
   --padding: 10px

.content {
   padding: var( --padding )


<div id="content-wrap">
   <div class=".content">
