Augments form labels to behave like placeholders, but with a twist.
jQuery Label Better will let you create a beautiful unobtrusive label for your form's input fields with animation. The uniqueness about this plugin is that all you have to do is add a placeholder text, and we will show the label only when the user needs it.
In-Field Labels is a simple jQuery plugin that turns properly formatted HTML forms into forms with in-field label support. Labels fade when the field is focussed and disappear when text entry begins. Clearing a field brings back the label.
