Position Absolute is sharing an easy to use form validation engine built with jQuery.

It offers a flexible way of displaying errors that will possibly match any type of form design. When the script detects an error, it creates a div, positions it at the right-top corner of the input & displays it like a tooltip with the error message inside.

jQuery Form Validation

Validation rules are created inside the classes of every input field like:
