Once again, we find ourselves opening up our favorite IDE and looking jQuery straight in the eye. However, instead of a complex script that controls an alien mothership, we are going to build some really simple, yet useful, tabs. Even though jQuery UI offers some pretty cool tab objects, it is still a very large library and sometimes you just need some simple tabs. Today, we are going to tackle this.

In part one, we covered the basics of how Drupal themes work and the base files that are used. We left off on template files, which are the heart of Drupal themes. Today we are going to continue with template files and give some examples of ones every theme will most likely use.

CSS is a powerful beast, and an essential part to any self-respecting website. With all this power, comes a lot of different tricks that one can employ to accomplish your tasks. Some of these tricks involve positioning your content, and today we are going to touch on that. For this tutorial we are going to reveal some of the best ways to center your content, wherever that content might be.

In part 1, we went over the creation of a basic jQuery popup plugin. While this is very useful in itself, it is not that flexible yet. This time around we are going to add a few new features that will make our popup plugin way more flexible and useful. So come on and find out what cool things we will make our popup do.

One of the most talked about technologies on the web right now is node.js, which is a server side implementation of JavaScript. That's not really anything new, but what is new is how it's built. The framework is built on top of Google's v8 engine, which is lightning fast. It's made to create "scalable network programs" by making nearly everything work asynchronously.

While the jQuery UI library is quite powerful, and mighty impressive, its footprint is sometimes a bit too much for the project at hand. The UI library also tends to "take over" your HTML, moving it, adding classes, and sometimes even changing attributes around. This can make styling and customizing your UI elements a bit of a pain, especially when you need a custom solution. This is why sometimes you need a UI solution, using jQuery, but without the jQuery UI. Today we are going to work on a draggable popup.

Recently, I have been playing around with building web applications for the iPhone and really wanted to try make the experience as close to a native application as possible. One big way to make the experience much better is by caching the application so it can be used offline. So, that's what I am going to show you how to do today. We are going to be using a new feature in HTML5 called a Cache Manifest file. This file will allow you to tell the browser to cache the application for offline use.

For nearly all problems there are probably a hundred different solutions. Recently one solution I have chosen for a few problems has been a Javascript bookmarklet. A bookmarklet is a regular bookmark that runs a bit of Javascript code instead of just going to a link. They are really useful for doing a small task on a website or webpage that you don't have direct access to the backend or source of. So, today I am going to show you how to make a simple bookmarklet.

Remember back many moons ago when we posted a previous tutorial about Excel document creation? Specifically, this one. It worked, but if you take a look at it again, that code was painful. And ugly. And required hooking up ruby with a Java library called JExcelAPI using RJB - which, really, is not something anyone actually wants to do. So today we are going to take a look at something else (that I think) is a lot nicer/cleaner for Excel document generation: a new web service specifically for document creation called Doc Raptor.

HTML5 is really hot all over the web right now so I figured I would drop some HTML5 knowledge on y'all. I have worked with Flash and Flex consistently for the last few years so I can easily drop and manipulate graphics in it, but I haven't done much with HTML5. This lead me to try and challenge myself to recreate something I built in Flash in HTML5. That is what we are going to look at and learn to build in this tutorial.
