Lightweight and very robust little jQuery plugin that generates the look and feel of the HTML5 placeholder attribute for browsers without native support. It also adds an extra title in case the placeholder text is too long to be displayed. The polyfill comes with an option to define if the placeholder text should be read to screenreaders or not (on by default). New in version 1.9 is the option to make it behave like Chrome or mobile Safari (hide placeholder when the users enters content rather than when the fields receives focus).
To see the actual work of this polyfill use an old browser like Firefox 3.6!
Modernizr (tested with 2.0.6) OR yepnope.js
fontresize (excellent even though terribly unmaintained event plugin that fires when a user changes the font size of their browser (that usually breaks the other placeholder polyfills))
The placeholder attribute has decent support across current Browsers. This script adds support for the older generations including:
For more details on native support see the browser suppport table at caniuse.com.
You can install HTML5 placeholder Polyfill by using Bower.
bower install html5-placeholder-polyfill

Please bear in mind that every input needs a linked label in order for the plugin to work.
