I think the transition from web design to user experience design is a natural process, just as the Internet has evolved from static display pages to more user interaction-oriented applications.

In my opinion there are several main reasons that have contributed to this shift. First, with the continued development of HTML5, CSS3, and JavaScript, web pages are no longer just static collections of images and text, but allow for more complex interactions and dynamic effects. This provides designers with more room for creativity, while also placing higher demands on design. Second, the popularity of smartphones and tablets allows users to access the Internet anytime and anywhere. This fragmented usage scenario requires designers to pay more attention to the user’s experience on different devices, rather than being limited to the traditional computer screen. Third, users are no longer satisfied with simple access to information; they want websites and applications to be more personalized, smarter, and more responsive to their needs. This has pushed designers from focusing on visual design to focusing on user psychology and behavior.
