How to hightlight source code using codemirror on a html page

I am currently highlighting the source on my website using google's prettyprint like below on my website.

<pre class="prettyprint css">
  div {
    background-color: lightgreen;
    width: 300px;
    padding: 25px;
    border: 25px solid red;
    margin: 25px;
}
</pre>

I will already have some code on file but I only want to hightlight that code. How can I highlight the same using codemirror?

as it shown in codemirror.net

create an <textarea> element, which will replace yuor current <pre> tag. set textarea to readonly if you prefer no edit.

<textarea id="myTextarea" readonly>
... your code for highlighting goes here ...
</textarea>

<link rel="stylesheet" href="lib/codemirror.css">
<script src="lib/codemirror.js"></script>
<script>
  var editor = CodeMirror.fromTextArea(document.getElementById("myTextarea"), {
    lineNumbers: true
  });
</script>

multiple instances selected by a common class name:

var areas = document.getElementsByClassName("myTextareaClass");
for(var i = 0; i < areas.length; i++) {   
  CodeMirror.fromTextArea(areas.item(i), {lineNumbers: true});
}
