Web development is the process of creating websites and web applications. It starts with planning, deciding what the site should do and how it should look. Then, HTML is used to build the structure of the pages, CSS is used to design and style them, and JavaScript is used to make the pages interactive. Developers also work on the backend, which handles data, databases, and server logic. Finally, the site is tested, optimized, and deployed so users can access it online.
