This plugin positions your labels on top of your form fields (similiar visually to placeholder) and makes the label slide across the field when gaining focus and fade out when a value is entered.
Seems OTT to me,<p>I generally use normal boring labels, then modernizer to detect if the browser supports placeholders, if so hide the labels and add placeholders to the attributes
how do you get the labels back again? sometimes my browser or password manager fills in the wrong fields, and, once there's something in the fields, there's no labels.
