Can't load theme because of a css error (I assume)

Hello, I’m trying to use codemirror with a theme, but it does not work and the console shows the error
"Uncaught SyntaxError: expected expression, got ‘.’ " in 3024-night.css:11
I checked the line and couldn’t understand what the problem is though.

I am new to Codemirror so it is of course possible I made a setup mistake.
Side note: if I remove the theme import and tag inside everything else works just fine.
This is the relevant code:

<script type="text/javascript" src="js/codemirror-5.60.0/lib/codemirror.js"></script>
<link rel="stylesheet" href="js/codemirror-5.60.0/lib/codemirror.css">
<script type="text/javascript" src="js/codemirror-5.60.0/mode/clike/clike.js"></script>
<script type="text/javascript" src="js/codemirror-5.60.0/theme/3024-night.css"></script>
<!--search libs-->
<script type="text/javascript" src="js/codemirror-5.60.0/addon/search/search.js"></script>

<link href="js/codemirror-5.60.0/addon/dialog/dialog.css" rel="stylesheet">

<!--klammern verbinden-->
<script type="text/javascript" src="js/codemirror-5.60.0/addon/edit/matchbrackets.js"></script>
<!-- klammern automatisch schließen-->
<script type="text/javascript" src="js/codemirror-5.60.0/addon/edit/closebrackets.js"></script>

<script type="text/javascript">
var editor;

$(function() {
	setTimeout(function() {
		editor = CodeMirror.fromTextArea(document.getElementById("codeTextArea"), {
			mode: "text/x-java",
			theme: "3024-night",
		    lineNumbers: true,
		    indentUnit : 4,
		    indentWithTabs : true,
		    autoFocus: true,
		    smartIndent: true,
		    highlightSelectionMatches: true,
		    matchBrackets: true,
		    autoCloseBrackets: true
	}, 200);


You appear to be trying to load a CSS file as a script here.

Ah my apologies, did not pay attention to that. Thank you!
