Web design encompasses the aesthetic and functional creation of a website or mobile web application. It involves designing all the graphic elements necessary to bring the site to life, including defining the style guide, creating images and illustrations, implementing navigation, and choosing typography.

In France, the term "web design" has undergone significant semantic evolution over the years, reflecting changes in the field. In the 1990s, "web design" was used to describe the creation of websites, encompassing both visual and functional aspects, from page structure to interface aesthetics.

Around the turn of the millennium, the term "web design" gradually replaced "web design," placing greater emphasis on the aesthetic and creative aspects of website design. This transition aimed to professionalize the field and distinguish it from web development.

From the 2010s onward, a trend emerged toward using more specialized terms to describe the various disciplines of the web. "UX design" focuses on optimizing the user experience, while "UI design" focuses on the visual and interactive aspects of interfaces.

The evolution toward increasingly complex web applications has given rise to new disciplines such as "interaction design" and "service design." These fields aim to design seamless and intuitive interactions between the user and the digital product or service, meeting the needs of a high-quality user experience.
