  • Patent number: 10788962
    Abstract: A webpage display method performed by a terminal device includes displaying a webpage on a screen, receiving a selection by a user with respect to an image included in the webpage displayed on the screen, and displaying, on the screen, a dynamic object responsive to the user selection of the image. The method further includes performing a predetermined function corresponding to the image while displaying the dynamic object on the screen. The dynamic object floats on the screen independently from the movement of the webpage on the screen, and is not displayed on the screen while the webpage is displayed on the screen, until the selection of the image. The dynamic object is removed from the screen while the webpage is still displayed on the screen when the predetermined function corresponding to the image is completed.
