What is Web Development?

Web development is the comprehensive process of building and maintaining websites and web applications that run on the internet or intranet. It encompasses everything from creating simple static web pages with basic HTML and CSS to developing complex, dynamic web applications with sophisticated user interfaces, database integrations, and real-time functionality.

The field of web development is traditionally divided into three main areas: frontend development (client-side), backend development (server-side), and full-stack development (combining both). Frontend development focuses on the user interface and user experience, dealing with everything users see and interact with in their web browsers. Backend development handles server-side logic, database operations, and application architecture that powers the frontend experience.

Modern web development has evolved far beyond basic website creation. Today's web developers build progressive web applications (PWAs), single-page applications (SPAs), e-commerce platforms, content management systems, social networking sites, and enterprise software solutions. They work with APIs, microservices, cloud platforms, and emerging technologies like artificial intelligence and machine learning integration.

The discipline requires an understanding of multiple programming languages, frameworks, libraries, and tools. Developers must consider factors such as performance optimisation, search engine optimisation (SEO), accessibility, security, mobile responsiveness, and cross-browser compatibility. The rapid pace of technological change means web developers must continuously learn and adapt to new tools, frameworks, and best practices.

Frontend Development Technologies

HTML, CSS, and JavaScript Fundamentals

HTML (HyperText Markup Language) forms the structural foundation of every web page, providing semantic markup that defines content hierarchy and meaning. Modern HTML5 introduces semantic elements like <header>, <nav>, <article>, and <section> that improve accessibility and SEO while providing clearer document structure. HTML also includes advanced features like Web Components, which enable creating custom, reusable HTML elements.

CSS (Cascading Style Sheets) handles the presentation layer, controlling layout, colours, typography, animations, and responsive design. CSS has evolved significantly with features like Flexbox and CSS Grid providing powerful layout capabilities, CSS Custom Properties (variables) enabling dynamic styling, and CSS-in-JS solutions bridging the gap between styling and JavaScript logic. Modern CSS preprocessors like Sass and Less extend CSS with variables, mixins, and functions, while PostCSS provides a plugin-based approach to CSS processing.
