Getting Started
Simply embed the following code in your page, after you've included jQuery, and preferably at the bottom of the page:
<!--[if lte IE 9]><script src="//yumpdigital.github.io/Advanced-HTML5-Placeholder-Polyfill/js/jquery.placeholder.js"></script><![endif]-->
Example
View this page in IE 9 or below to view the polyfilled placeholder.
