Web and WordPress Development
This website has been going, in one form or another, for the past 22 years. That’s really quite a long time, as websites go.
First there was The Elated Web Toolbox, built in 1997 with my jolly good friend and business partner Simon and packed with freebies for webmasters such as web templates, free images, and web design and Photoshop tips.
The Ruby programming language is becoming increasingly popular, thanks to its clean syntax, its object-oriented features, and its range of high-quality libraries and frameworks.
In this tutorial, you get a gentle introduction to programming in Ruby. You learn:
At the end of the tutorial, you also explore some resources for taking your Ruby skills further.
Let’s start with a brief introduction to Ruby, and take a look at the language’s features and benefits.

In my tutorial Build a CMS in an Afternoon with PHP and MySQL, I showed how to build a simple but useful content management system with PHP and MySQL. I also showed how to extend the CMS to allow article categories.
In this tutorial, you’ll look at another way to extend the CMS. You’ll take the original CMS code, and modify it so that the administrator can upload an image for each article. Then, when a visitor views an article page, the CMS will display the image at the start of the article. In addition, our CMS will generate a smaller thumbnail version of each article image, and display this thumbnail next to each article headline in the homepage and article archive pages.
You can see the finished result by clicking the View Demo link above. Notice the thumbnail images next to each article headline. Click a headline or thumbnail to view the corresponding article, along with the full-size article image.
Many modern websites — and practically all web apps — use a technique called Ajax to provide a smooth, fast experience for the user. From apps like Gmail and Google Maps through to JavaScript frameworks like jQuery Mobile, Ajax is a popular way to fetch data from a server in the background and update the page dynamically.
Writing Ajax JavaScript code from the ground up can be fiddly. However, many JavaScript libraries, including jQuery, have excellent high-level support for Ajax, making it easy for you to build Ajax-driven websites and apps with minimal hassle.
In this tutorial, you’ll learn the basics of making Ajax requests using jQuery. You’ll look at:
To keep things simple, this tutorial concentrates on the JavaScript side of things, rather than delving into server-side coding. However, it’s pretty easy to write server-side scripts that work with Ajax. If you want to learn a server-side language, check out my PHP tutorials.

Since publishing my tutorial Build a CMS in an Afternoon with PHP and MySQL, many readers have asked how to add more features to the CMS. I thought I’d answer some of these questions by writing additional tutorials that build on the original simple CMS.
In this tutorial, you’ll learn how to add article categories to the CMS. Categories give your site more flexibility: as well as listing all articles on the homepage, you can create separate section pages of your site, with each section page listing the articles belonging to a particular category.
For example, our original CMS demo lumps all types of article — news, reviews, and interviews — together on both the homepage and the archive page. By creating separate News, Reviews, and Interviews article categories in our CMS, we can then create individual archive pages for news, reviews, and interviews in our site.
You can see how this looks by clicking the View Demo link above. Notice that each article title on the homepage has a category name below it (Interviews, Reviews or News). Click a category to view its archive page, which lists all articles in that category, along with the description of the category at the top of the page.

As mobile web browsing becomes more common, it’s increasingly important to design websites for mobile use as well as for desktop browsing. This can mean anything from tweaking your regular site so it looks OK on Android and iOS devices, through to CSS media queries, responsive layouts, and even completely separate websites for mobile users.
The question is: How do you make a website work well on a mobile browser? It helps to start out by thinking about how the mobile browsing experience differs from desktop browsing. In this article I’ll touch on 10 important factors that make the mobile web different, and show how you can use those factors to influence your mobile site design decisions.
Contact forms can be useful way for visitors to contact the owner of a site. They’re easy to use, and since they don’t expose the site owner’s email address in the page, they cut down on spam too.
However, contact forms can also be cumbersome, especially as they’re usually on a separate page. The visitor has to visit the contact form page, fill in the details, view yet another response page, and then try to make their way back to the page they were originally reading.
Fortunately, Ajax gives us a way round this problem. By embedding the form in the page, and submitting the form data via Ajax, the user never has to leave the current page. It also provides a smoother experience for the user.
In this tutorial we’ll build a nice-looking, embedded Ajax contact form that the user can summon up by clicking a link in the page. Along the way, we’ll explore various topics, including:
Before you begin, check out the finished product by clicking the View Demo button above. This opens a new page with some dummy content, and a couple of “Send us an email” links. Click one of these links to display the form.
The demo doesn’t actually send an email anywhere, but the finished code in the download is fully functional. To get the code, click the Download Code button above.

Like most programming languages that support functions, PHP lets you write recursive functions. In this tutorial, we’ll explore the concept of recursion in PHP, and discover how to create recursive functions for various tasks.
Recursion is one of those topics that can seem confusing at first, but once you start writing recursive functions you’ll see how elegant recursion can be!

Recently, a reader asked us how we created our floating orange “follow” tab that appears on the right-hand side of every page on elated.com. It’s quite a nice effect and it also uses some interesting new CSS3 features, so I thought it’d make a good topic for a tutorial!
In this tutorial you’ll learn how to:
