Since Matt published his tutorial Build a CMS in an Afternoon with PHP and MySQL, many readers have asked how to add more features to the CMS, such as article categories and a visitor comments system.

In this tutorial, you learn how to add article categories to the CMS. Categories give your site more flexibility: you can create separate section pages of your site, with each section page listing the articles belonging to a particular category.

The tutorial includes the full CMS code - including category support - as a downloadable zip file.

jQuery Mobile is a great framework for building mobile web apps, and as the 1.0 release gets nearer it's really starting to mature into a stable platform.

In this tutorial you'll delve deep into jQuery Mobile. You'll build a simple, nice-looking, easy-to-use iPhone Twitter app called "CloseFriends" that displays your closest Twitter friends' latest tweets.

Along the way you'll explore a variety of topics, including jQuery Mobile's API, the Twitter API, HTML5 local storage, app theming, media queries, and lots more!

Responsive web design is a hot topic these days, especially as websites need to adapt to the growing number of mobile devices with their relatively small screens.

However, the whole topic can be somewhat bewildering at first glance. Responsive design is a relatively new idea, and it is rapidly evolving. It's full of rather confusing terms, such as responsive layouts, adaptive layouts, media queries and viewports. Where to begin?

In this article, you get a gentle introduction to the world of responsive web design, and learn how to create a simple responsive website layout.

As you start to use JavaScript to build larger and larger web apps with complex data structures and rich user interfaces, it becomes clear that the JavaScript language alone is not really up to the task.

Fortunately, some great JavaScript libraries have sprung up in recent years to make your life as a web developer much easier.

In this article, Matt Doyle focuses on five fairly recent libraries and technologies that are starting to gain traction: Backbone, Underscore, Knockout, Sugar, and CoffeeScript.

A database is an essential part of most websites and blogs, but setting up and using a database can be a daunting task for the beginner web developer.

In this tutorial you learn - in simple terms - how to install, set up, and use a MySQL database on your computer. This will give you a good grounding in MySQL that you'll find useful when you start developing database-driven websites using PHP, Ruby, or your language of choice.

Three.js is a fantastic JavaScript library that lets you create realistic, animated 3D scenes, right in the browser. However, while Three.js is relatively easy to use, it can still be daunting if you're not familiar with the concepts involved in computer-generated imagery.

In this tutorial, you get a gentle introduction to Three.js's features and concepts, and you then put your new-found knowledge to practical use by creating a rotating 3D boxshot scene.

Enjoy!
