You have a small area. You mouse over it. An area pops up giving you a zoomed in closer look. AnythingZoomer is a jQuery plugin that does it.
It’s flexible in many ways, in that the “smallâ€, “largeâ€, and “zoom†areas are all pretty easy to customize via CSS. It’s inflexible in other ways, in that it doesn’t “automatically†work by cloning content or anything like that (which is arguably more flexible), and the HTML structure is fairly rigid.

On blogs that like to share snippets of code, it is common to use the <pre> tag to wrap the code so that the spacing/indenting is maintained and long lines do not wrap. While this is desirable behavior, it can be undesirable to have those un-wrapped lines break out of their containers awkwardly and overlap other content.
On Digging Into WordPress, they taught us How to Make an Expanding Code Box by using JavaScript (jQuery) to solve this problem. One solution could potentially be to use only CSS and expand the width with something like pre:hover, but JavaScript is more elegant. It expands only when needed. It expands only to as wide as needed. And also, it expands with animation.

MattBango has shared his approach to creating a timeline out of CSS and HTML. The Pure CSS Timeline is a simple and clean looking timeline with some very straight forward markup. We have a nice looking timeline styled completely with CSS, but what happens if the visitor doesn’t have CSS enabled? Since we used unordered lists, we still have a nicely accessible list of events.
The Pure CSS Timeline may not be the perfect solution markup wise and CSS wise, but it gets the job done and is still quite accessible for all users. Take the timeline a step further. You could add some Javascript interactions, tooltips, animations, etc.

Today we’re going to break the mold of the traditional tooltip. This tutorial will demonstrate how to build tooltips that are powered by jQuery, with information pulled from a JSON array. Here’s a look at the final result that we’ll be looking to make:

Our page will have two links. When a user hovers over a link, it will trigger the top banner to change its background image and text based on the entry in a JSON array. See the Demo
We’ll be using a pack of background images in later steps. You can grab those here.
Build the Page Structure
New File: I have called my HTML file ‘json-tooltip.htm” for this tutorial
Our example’s HTML is pretty self explanatory. We’re just blocking out a banner to contain the tooltip information, and then placing all of the normal content below.
Pay special attention to what’s going on with link anchors with a class of “tooltip” though. This is the class that will designate which links are tooltips. Also, you’ll notice that the “rel” attribute contains a number. This is the number we’ll use to associate a specific tooltip to an anchor link. This will become clear in a few steps.

Would you like the Scrolling Background Effect like youlove.us? The technique is actually a lot simpler than it looks, it’s based around scrolling a very tall gradient image behind some transparent PNG images. The header image has a transparent background and solid text, while the main page is actually an image with the heading text as transparent cut outs.
The JavaScript is where the real magic happens. They have made use of the jQuery library and Alexander Farkas backgroundposition.js script to help them make the background move. The final result looks very nice. However, it might consume a lot of your CPU resources.

With 200 lines of JavaScript, you can drag and drop table content. Content of the HTML table cells can be dragged to the another table cell or another table. Script has built in autoscroll and option to forbid landing to some table cells. Table could have rowspan or colspan cells and different background color for every cell.
In order to detect destination table cells, script calculates all table cell coordinates / dimensions and store them to the arrays. Arrays are searched inside onMouseMove handler and when user release left mouse button, object will drop to the current table location.

Requirements: FireFox 3, Internet Explorer 6 and Google Chrome

While mimicking the OS X dock and stacks isn’t new, it’s certainly not common. Nettuts has shown us a few ways to do “Outside the Box†Navigation with OS X style docks and stacks navigation.
jQuery OS X Stack and Drop Stack is my favorite navigation style out of the three shown in the tutorial. It’s super lightweight (~1kb). It might be a little awkward having the navigation in the bottom right or left of the browser window but it would certainly be creative and save lots of space.

Ever wanted those flash iPhone on/off toggle switches on your webpage? Love jQuery? Well then Thomas Reynolds has got something special for you. iPhone Style Checkboxes implements the iPhone toggles as replacements for standard HTML checkboxes.
Simply run the script and your site will be updated with these specialized controls. Best of all, the underlying checkbox is not touched and backend system will never know the difference. The change is purely visual.

Many websites offer syndication formats such as RSS, JSON, or XML based services to allow for easy content delivery. But what happens when a website doesn’t offer one of these services? How do you syndicate content from a website that doesn’t offer a news feed?
Nettus has gaven us a a simple solution using JQuery’s AJAX functions and PHP’s cURL library that allows us to syndicate external content. This is a simple solution if you require content from an external website.
Although JQuery’s easy syntax and CSS-selectors give us the convenience of styling and selecting what we want from the client-side, this is not speed optimized. Remember you have no control over whether or not the content creator changes what tags and classes they use, it is always best to style general elements that will be commonly used.
