One of the nice enhancement in HTML5 web form is being able to add placeholder text to input fields. Placeholder attribute allows you to display text in a form input when it is empty and when it is not focused (it clears the field on focus). This is a nifty feature, but it is not supported by all browsers yet. This tutorial will show you how to use Modernizr to detect if placeholder is supported, or else use jQuery to display the fallback placeholder text dynamically.

Credits: thanks to Darcy Clarke (my Themify's partner) for the jQuery and Javascript code.

The script finds your current view position and scroll to the next or previous post accordingly. Check out the demo to see what I'm talking about.
