Hot!Ajax

InnerFade is a small plugin for the jQuery-JavaScript-Library. It's designed to fade you any element inside a container in and out.

These elements could be anything you want, e.g. images, list-items, divs. Simply produce your own slideshow for your portfolio or advertisings. Create a newsticker or do an animation.

Finally a lightweight accordion that is built with scriptaculous and works properly in every browser.

LightForm is a free Ajax/PHP contact form. It also uses FormCheck2 for fields validation and NiceForms to style text fields and textareas.
