Here is a clear difference between UX/UI design and web design:
User experience design, or UX design, is often the unnoticed or "behind the scenes" aspect of design. It is all the labor that is put into developing a program, website, app, or service. Information architecture, interface design, usability testing, and content strategy are all components of user experience design.
User interface design, often known as UI design, is the graphic or visual component of design. While some UX designers will also work on some UI, others will stop at research and wireframes. Whether you want to do it yourself or so you can work more effectively with UI designers, there is a course on UI design on the OpenClassrooms UX designer route.
The process of organizing, producing, and artistically displaying content and information on the internet is known as website design. It may cover a range of topics, including as graphic design, content creation, and website layout. Web design often consists of a variety of visual elements that are designed to emphasize and enhance a company's identity, such as textual material for headlines and body copy, photos, videos, fonts, colors, and graphical elements.
