Some javascript code that makes article element "content editable" with limited rich text editing capabilities. I hate javascript btw. so do not contact me about javascript related things.
Don't. If you feel compelled to do so, first include the script
<script type="text/javascript" src="some-assets-directory/contenteditable.js"></script>
then get selector for your favorite article element and initiate the editor like below.
<script type="text/javascript">
var editor = new ContentEditable("#TheSelector");
</script>
