Abstract: Digital content view control is described as leveraging a hierarchical structure of objects defined within the digital content to control how those objects are rendered in a user interface. In one example, a user input is received to display a view of objects within digital content displayed in a user interface. In response, a data query module is configured to fetch data describing a hierarchical structure of the digital content. From this, a z-order determination module determines a z-order of objects included with the digital content. An object view generation module is also configured to generate object views depicting the objects included in the digital content. The object views, once rendered, support an ability to view positioning of objects within the hierarchy.
