Frontend refers to the part of a website or application that users interact with directly. It includes everything that users see and experience, such as layout, design, buttons, and images. Frontend development involves using languages like HTML, CSS, and JavaScript to create visually appealing and functional interfaces. Frontend developers focus on ensuring that a website is user-friendly and responsive across different devices. They work closely with UI (User Interface) and UX (User Experience) designers to implement designs and improve usability. The goal is to create an engaging experience that meets the needs of users while maintaining performance and accessibility.
