Which role focuses on the visual components of a website?

The focus of a front-end developer is on the visual components and user interface of a website. This role involves creating the part of a website that users interact with directly, ensuring that it is not only aesthetically pleasing but also functional and responsive to different devices. Front-end developers use technologies such as HTML, CSS, and JavaScript to build layouts, style elements, and add interactive features, ensuring a seamless user experience.

In contrast, other roles such as back-end developers primarily deal with server-side programming, database administrators manage and design databases, and network engineers focus on network architecture and connectivity, which do not directly involve the visual elements of a website.
