Which aspect is NOT typically a responsibility of a web developer?

The aspect that is not typically a responsibility of a web developer is the creation of the visual components of a website. This task is more aligned with the role of a web designer, who focuses on the aesthetics and user experience elements of a website.

Web developers primarily concentrate on the technical aspects, including writing HTML and CSS code, ensuring the site functions properly through implementing functionalities, and even managing the back-end processes like maintaining web servers. While some web developers may have skills in design and can create visual components, their core responsibilities tend to lean more towards coding, application logic, and server management, rather than the creative aspects of design.
