If you only want to change the appearance of certain words/sentences (e.g. highlighting), you could use the [Custom Styles](https://ankiweb.net/shared/info/1899278645) add-on.
If you want to change the styling of the editor itself, there’s the add-on [Customize Editor Stylesheet](https://ankiweb.net/shared/info/1215991469), but it won’t allow you to edit _everything_ because the field’s default styles are protected within a shadow-DOM. You can see this in action when you inspect fields with [AnkiWebView Inspector](https://ankiweb.net/shared/info/31746032).

To fully control the look of elements inside Anki’s editor fields, you need to inject your CSS into the shadow-root with your own add-on:
(The Custom Styles add-on does the same thing, but you can only change the injected stylesheet through the add-on interface, which is a little bit limited.)

> @kleinerpirat There’s [this PR](https://github.com/ankitects/anki/pull/1049) which would certainly help you out. Besides that, you can only access it with add-ons. A somewhat minimal example for the Python part would be load\_collapsible\_icon\_js in [Collapsible Fields](https://github.com/hgiesel/anki_collapsible_fields/blob/master/src/webview.py). Of course, you’d only need the CSS file. A minimal example for the JS/CSS would be [the load function here](https://github.com/hgiesel/anki_persistent_editor/blob/master/web/editcurrent.js#L66) in load. You’d need to adjust textContent (or load it through a link element with href).
