Web Development is the process of creating and maintaining websites. It encompasses various aspects, including web design, web programming, and database management. Developers use languages like HTML, CSS, and JavaScript to build the visual and interactive elements of a site. In addition to front-end development, which focuses on the user interface, web development also includes back-end development. This involves server-side programming and database management, often using languages like PHP, Python, or Ruby. Together, these components create a seamless experience for users navigating the web.
