Organisations that already use .NET often want a content management system their developers can maintain with the same language and tools. Orchard Core is an open-source CMS built on ASP.NET Core. Site editors manage content themselves through the admin area,…
Once you can write C# comfortably, what separates professional code from code that merely works is a deeper grasp of how the language behaves: flexible object-oriented design, memory management, generics, delegates and LINQ, and asynchronous and multithreaded…
Yii is a PHP framework that many organisations use to build medium to large web applications. Its latest generation, Yii3, reached its first stable release at the end of 2025. It is a complete rewrite as a set of separate packages built on PSR standards and…
Once a website works on every screen size, the next step is to give it character and make it a pleasure to use, with crisp icons, smooth mobile menus, scroll effects and gentle page transitions. These used to need jQuery and many plugins, but today the…
Most people switch between phones, tablets and computer screens of many sizes throughout the day, so a good website must stay easy to read and use on every screen. Responsive web design is the set of ideas and techniques that lets a single page stretch,…
HTML and CSS are the foundation of every web page. HTML5 lets you build forms, add audio and video and structure pages without plug-ins such as Flash, while modern CSS brings Flexbox, Grid and media queries so sites look good on every screen size. Add…
HTML and CSS can now do far more than lay out pages. Much of what once needed large JavaScript libraries, such as tooltips that stay attached to a button, scroll-linked animation, smooth page transitions or reusable components, is now built into the browser.…
Although many new APIs use JSON, XML is still the main data format wherever structure must be strict and verifiable: banking, insurance, government, electronic documents, Office files, SVG, sitemaps and the SOAP web services organisations still use to connect…
jQuery is a JavaScript library that makes it quick to select elements, change the DOM, handle events and make Ajax calls with short code, and it is still found on a great many websites, including internal systems and WordPress and other CMS themes and…
Joomla is still the open source CMS behind many websites in government agencies, schools and organisations. The whole look of a site depends on its template, yet many sites still run old templates that cannot be upgraded, or have edits made directly to the…
Ajax lets a web page send and receive data from the server without reloading the whole page, so it underpins instant forms, search boxes with suggestions, shopping carts and almost every back-office system. Browsers now provide the Fetch API as standard, many…
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…
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…
