It may seem confusing at first. Especially because both UX and UI complement each other and even at times work in unison. These terms are often mistaken from each other too vaguely to concretely understand and distinguish the two. At the most intrinsic level, the UI creates the presentation and productivity of a website. Basically, it is the functioning skeletal structure of a website and how it operates. Let’s say you have the UI running smoothly but the links load slowly, the images don’t show up and the search function feels unresponsive and shows ambiguous results. Those errors and problems are usually handled by a UX designer. These are both important aspects in order for a user to enjoy a product.
