Instructor-led IT courses across web, mobile, data, design and more.
Documents are basic work in every organisation: letters, memos, reports and forms. Many people have used Word for years but still lay out pages by pressing Space and Enter repeatedly, so a small edit pushes the formatting across the whole page, files end up…
Google's results page is no longer just ten blue links. Searchers now see AI Overviews, AI Mode, rich results, local map packs and products on the same page. Many website owners and marketers are unsure what to do differently, and some turn to shortcuts or to…
Most users reach the web from their phones, and many organisations want apps for staff or customers without building separate Android and iOS apps. A Progressive Web App, or PWA, is a web app designed to work well on mobile, install on the home screen, keep…
C# is Microsoft's object-oriented language for building web APIs, desktop apps, games and cloud services on .NET, an open-source platform that runs on Windows, macOS and Linux. Its C-style syntax makes it easy to pick up for anyone who has written C, Java,…
Programming underpins almost every area of IT, from websites and mobile apps to desktop software and systems that work with data. Even with AI now helping to write code, people who understand how programs and data are structured are still needed, because…
MySQL is one of the databases web and app developers use most, yet many systems still write queries the old way: pulling data into code to loop over it, building SQL by concatenating strings and so risking SQL injection, or relying on deprecated features. As…
There are several ways to sell online: through a marketplace, by renting a hosted shop builder, or with a store website of your own. The last option gives you full ownership of your customer data and storefront, and OpenCart is an open-source online store…
WordPress is a widely used content management system because it lets you build a website without writing code. Visitors see the front end, while site managers use the admin area to manage the design, posts, images and products themselves. Current WordPress…
Joomla is an open-source CMS used to build websites for organisations, agencies, schools and multilingual sites out of the box, without programming. It has systems for managing articles, menus, users and fine-grained access permissions. The current release is…
jQuery is still part of many websites, back-office systems and plugins in organisations, and jQuery 4, released in 2026, removed a number of old APIs and dropped support for old browsers. Work that once relied on older plugins, such as jQuery Templates or…
JavaScript is the one language every browser understands, so it sits behind almost every button, menu, form and interactive screen on the web, and it is also the foundation of React, Vue, Node.js and many other modern tools. Yet many beginners learn from…
Java is still the main language behind many enterprise, banking and backend systems, but the language has changed a great deal in recent years. Many books and examples still teach Java 8 style, with long code and no records, pattern matching or virtual…
Enterprise web applications must do more than show pages and save data. They must serve many users quickly, connect reliably to other systems, update in real time, run heavy work in the background without making users wait, protect sensitive data and tell the…
ASP.NET 4.0 and Web Forms were once the main way to build business web applications on the Microsoft platform, but Web Forms is no longer being developed and is not part of modern .NET. Today, web applications on .NET are built with ASP.NET Core, which runs…
Many PHP websites start as procedural code that is quick to write and easy to follow. As the system grows, functions end up scattered across every file, SQL is mixed with HTML, and a change in one place breaks several others until nobody dares to touch it.…
PHP and MySQL still power a great many websites and business systems, yet much of the sample code around is written the old way: SQL built by joining strings, passwords stored unsafely, functions that have since been removed, or jQuery for everything. Sites…
PHP and MySQL still power a great many websites, from internal back-office systems and sites built on WordPress to frameworks such as Laravel. Understanding PHP and databases from the ground up is therefore a good way into web development. Yet much of the…
Every website we open today, whatever tool or framework built it, ends up in the browser as HTML and CSS. People who understand these two languages can edit pages, adapt templates and talk to development teams with confidence. Yet many beginners learn from…
Every major browser now supports HTML and CSS features that used to need JavaScript or third-party libraries: forms that validate themselves, dialogs and popovers, styling based on what an element contains with :has(), components that adapt to the space they…
