Code

Scrolling Divs: Scroll div content vertically or horizontally, onmouseover, onmousedown, onmousewheel or with a gliding motion onclick. Custom scrollbars and multiple instances are supported. Scroll areas can be positioned absolute or relative. New content can be swapped in and updated via ajax. Many more features and extras.
Tooltips: The JavaScript DHTML tooltip is unobtrusive and full-featured. It supports obtaining content via ajax, flexible positioning and formatting options, as well as hoverable, sticky, duration, and class swapping options. It can be used to display images, images with text, and other rich HTML. It includes accessibility and device independent features.
Rotate Images JavaScript: Swaps in images using a timer. Images can be linked. Optional pause and resume on mouseover. Multiple sets of rotating images can be included in a document. Supports random rotation, transition filter effect for Internet Explorer on Windows and optional rotating caption or title.
Rotate Images JS with PHP Extension: Extends the capabilities of the Rotate Images JavaScript to PHP. Rotating images can come from a directory listing or from query results. All the functionality of the JavaScript can be incorporated with the PHP data, including links, captions, and randomness.
Random Image Display: See two examples that display a randomly selected image each time the page loads, a PHP version capable of providing images from a variety of sources (database query, directory listing, static list you provide) and a JavaScript version, selecting from a static list of images you provide.
Change Font-Size Onclick: Object-based code to increase or decrease font-size by clicking on images, buttons or text links. Control the range of text size adjustment and control using selector text which elements' font-sizes can be changed and how much.
PHP Order Form: The Order Form is generated from an array of products and prices. One example includes a standard PayPal button for payment; the other includes contact information for sending an order email.
