The term "front-end" 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, and navigation. Front-end development involves using languages like HTML, CSS, and JavaScript to create visually appealing and functional interfaces. Front-end developers focus on ensuring that a website is user-friendly and responsive across different devices, such as smartphones and tablets. They work closely with designers to implement visual elements and enhance user experience, making sure that the site is both attractive and easy to use.
