I’ll also add that if you’re looking to do this in the editor, the selectors will be `.cm-header-1::before` for the H1 or `.cm-header::before` for all headers.

So, in summary:

```css
.CodeMirror-code > :not(.CodeMirror-activeline) .cm-formatting-header {
  display:none;
}
.CodeMirror-code > :not(.CodeMirror-activeline) .cm-header::before {
  content: "§ ";
}

```

(and if you want just H1s instead of all headers, use `.cm-header-1` instead of `.cm-header`)  
This is just for the editor, and untested
