Why does highlight not working on implement CodeMirror?

css for javascript is not working. Does not highlight. See this print screen: https://snipboard.io/TNDxut.jpg

I connect those files from codemirror and I add <pre> and </pre> before and after java code lines. And it is not working.

Can anyone help me? What did I miss ? What can I do to work my code?

This is my code from print screen:

<html>
<head>
<meta charset="utf-8">
<title>Code Mirror</title>

<script src="c:/Users/Castel/Videos/Code Mirror/src/codemirror.js"></script>
<link rel="stylesheet" href="c:/Users/Castel/Videos/Code Mirror/lib/codemirror.css">
<script type="text/javascript" src="c:/Users/Castel/Videos/Code Mirror/mode/javascript/javascript.js"></script>

</head>

<body>

<p>Bebe este acasa</p>

    <textarea id='demotext'>

    function foo() {
        for(i = 0, i < 10, i++)
        console.log(i);
    }

    </textarea>
<pre>
<script type="text/javascript">

    var editor = CodeMirror.fromTextArea(document.getElementById("demotext"), {
          lineNumbers: true,
          mode: "javascript"
    });

// Demo for running a CodeMirror parser over a piece of code without
// creating an actual editor.

(function(){
  function normaliseString(string) {
    var tab = "";
    for (var i = 0; i < indentUnit; i++) tab += " ";

    string = string.replace(/\t/g, tab).replace(/\u00a0/g, " ").replace(/\r\n?/g, "\n");
    var pos = 0, parts = [], lines = string.split("\n");
    for (var line = 0; line < lines.length; line++) {
      if (line != 0) parts.push("\n");
      parts.push(lines[line]);
    }

    return {
      next: function() {
        if (pos < parts.length) return parts[pos++];
        else throw StopIteration;
      }
    };
  }

  window.highlightText = function(string, output, parser) {
    var parser = (parser || Editor.Parser).make(stringStream(normaliseString(string)));
    try {
      while (true) {
        var token = parser.next();
        var span = document.createElement("SPAN");
        span.className = token.style;
        span.appendChild(document.createTextNode(token.value));
        output.appendChild(span);
      }
    }
    catch (e) {
      if (e != StopIteration) throw e;
    }
  }
})();
</script>
</pre>

I don’t think any browser will load from paths starting with c:/. Look into file:// URLs, that might help here.

ok, so I copy those files from codemirror folders into root, but is not working either:

<link rel="stylesheet" type="text/css" href="plugin/codemirror/lib/codemirror.css">

<script type="text/javascript" src="js/jquery.min.js"></script>
<script type="text/javascript" src="plugin/codemirror/lib/codemirror.js"></script>
<script type="text/javascript" src="js/default.js"></script>

I also have this java code with <pre> and </pre>

<pre>
<script type="text/javascript">
// creating an actual editor.
    var editor = CodeMirror.fromTextArea(document.getElementById("demotext"), {
          lineNumbers: true,
          mode: "javascript"
    });

</script>
</pre>
