I've started a jquery editor that will replace this here.
A Medium like inline editor
At a minimum, you must download the javascript file (production version or the development version) and the css styles for preview (production version or the development version) and the editor css style (production version or the development version).
In your web page:
<head>
...
<link rel="stylesheet" type="text/css" href="../dist/css/inline-editor-frontend.min.css" />
...
</head>
<body>
...
<div class="ied-content">
<div id="editor" class="ied-article">
<section class="col">
<h1>This is the title</h1>
</section>
</div>
</div>
...
<script src="jquery.js"></script>
<script src="../dist/inline-editor.min.js"></script>
<script>
jQuery(function($) {
$('#editor').inline_editor();
});
</script>(Coming soon)
