Abstract: A user device (e.g., a computing device, a smart device, a mobile device, a laptop, a tablet, a display device, etc.) may identify a duration of a loading time for a page (e.g., web page, application page, links and/or linked data, documentation, a screen, etc.) of a user interface, for example, based on a request to load the page. The user device may retrieve a structure of the page that indicates an arrangement of page elements of the page, for example, based on the duration of the loading time exceeding a time threshold. The user device may cause, for example, during the loading time, display of a preview page for the page. According to some aspects of this disclosure, the preview page may include an animated representation of the structure of the page that indicates various arrangements of the page elements.
