Web development involves building and maintaining websites. It encompasses everything from creating simple static web pages to complex web-based applications. Web developers use programming languages such as HTML, CSS, and JavaScript to bring a website’s design and functionality to life. They also work with frameworks and libraries to streamline the development process and ensure the site is responsive and user-friendly across different devices. Additionally, web developers often collaborate with designers, content creators, and other professionals to create a seamless online experience for users.
