Created February 5, 2013 09:15
Use placeholder Attributes as Label.
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<style>
[placeholder] { position: relative; }
/* not functional - attr(...) is not part of the shadow-dom parent element :-/;
[placeholder]::-webkit-input-placeholder::before { position: absolute; display: block; content: attr(placeholder); bottom: -1.5em; left: 0; color: #000; }
*/
/* but this is functional - in webkit Browsers */

Still, it's different in a lot of ways.

escape text for inclusion by innerHTML as one handy fully namespaced function
var escapeHTML = (function() {
var regexp = /[<>&'"\/]/g
, replacements =
{ '&': '&amp;'
, '<': '&lt;'
, '>': '&gt;'
, '/': '&#x2F;'
, '"': '&quot;'
, "'": '&#39;'
