Have you ever visit Apple's MobileMe website? The login screen has form labels that are written within the value of their associated input field.

Inline labels are nothing new – in fact the easiest way to label a field is to simply set the field value up front and blow it away when the field gains focus. This is handy way for designers to save space and make their designs cleaner all-around. Unfortunately for us developers, simply setting the input value isn't very semantic or usable then you can't do it simple. I've just use a little jQuery to make it all happen.

Lazy loader is a jQuery plugin written in JavaScript. It delays loading of images in (long) web pages. Images outside of viewport (visible part of web page) wont be loaded before user scrolls to them. Using lazy load on long web pages containing many large images makes the page load faster. Browser will be in ready state after loading visible images. In some cases it can also help to reduce server load. Lazyloader is inspired by YUI ImageLoader Utility by Matt Mlinac.

Lazy Loader
Lazy loading is a design pattern commonly used in computer programming to defer initialization of an object until the point at which it is needed. It can contribute to efficiency in the program's operation if properly and appropriately used.

Lightbox, and the newer Lightbox 2, is a JavaScript application used to display large images using modal dialogs. On a Lightbox-enabled page, a user can click an image to have it magnified in a Lightbox window, which resizes itself according to the size of the image using a gliding animation. Lightbox determines which images will be shown in the modal window through the XHTML "rel" attribute, which is used on an <a> element wrapped around the <img alt="" /> element. Lightbox also provides a way to attach captions to images and to run a slide show, which can be navigated using the arrow keys.

The script has gained widespread popularity due to its simple yet elegant style and easy implementation. While it was initially developed from scratch, Lightbox has since been modified to use a number of JavaScript libraries (such as the Prototype Javascript Framework and jQuery for its animations and positioning), in order to reduce the size of the code. The release of Lightbox encouraged other developers to work on similar projects, resulting in products such as 15+ promising jQuery Lightbox-Clones plugins.

Do you ever know the way to open a external link in a new windows or tabs is one of "The Top Ten Web Design Mistakes of 1999"?
Opening up new browser windows is like a vacuum cleaner sales person who starts a visit by emptying an ash tray on the customer's carpet. Don't pollute my screen with any more windows, thanks (particularly since current operating systems have miserable window management).
Designers open new browser windows on the theory that it keeps users on their site. But even disregarding the user-hostile message implied in taking over the user's machine, the strategy is self-defeating since it disables the Back button which is the normal way users return to previous sites.
I discovered right away is that the <a> tag does not allow the target attribute in XHTML Strict (nor does it in HTML Strict).

Open external links
However, the behavior of
<a target="_blank"'> can be replicated in XHTML Strict with semantic markup and scripting.

I don't use a lot of JavaScript, but as you probably know, I'm a fan of offloading things to other people when it can save me the hassle of doing it myself.
A CDN — short for Content Delivery Network — distributes your static content across servers in various, diverse physical locations. When a user’s browser resolves the URL for these files, their download will automatically target the closest available server in the network.
