**3.1 HTML5 visual interactive work "digital provider"**

HTML5 "the king's glory x digital provider program" was jointly launched by Tencent and Dunhuang Research Institute to spread Dunhuang culture and advocate the protection of Dunhuang murals. It has excellent performance in visual design, music and sound effects, interaction, and user experience (**Figure 1**). HTML5 focuses on the disappearing colorful Dunhuang murals that are fading their brilliant colors. The video is slowly unfolded in words, and with the animation of broken and peeling rock walls, it pulls users into the space and time of Dunhuang. Users come to mural selection interface, and then browse and enjoy 10 Dunhuang murals by sliding the screen horizontally, and then re-color and re-produce one of their favorite murals that have lost their color into the most beautiful Dunhuang in everyone's heart. They may enter their names to generate your own Dunhuang murals after painting and then freely choose to share or donate money for Dunhuang murals, becoming a digital provider and contributing to the protection of murals (**Figure 2**).

This kind of HTML5 focuses on feeling the charm of culture in the viewing process by satisfying users' audio-visual experience. The key to the success of this case is the appropriate connection between the expression form of creativity and emotion. The first is creativity. By clicking on the interactive form of color for the lost murals, users can achieve a sense of creative achievement in this process and personally feel the beauty of Dunhuang murals. In terms of expression form, the entire HTML5 adopts slow pace and simple tone. The visual design perfectly fits the gravel texture of Dunhuang murals and the traditional color matching of murals, enabling users to have an immersive experience. Secondly, sound and picture are combined in the program. In terms of design, bells and flutes in line with the theme tone are used, which greatly enhances the authenticity and beauty of HTML5 and generates the resonance between users and the disappearing Dunhuang murals.
