Computer-implemented methods for selectively pre-rendering off-screen content for display before the content comes on-screen on a device are provided. In one aspect, a method includes receiving a request to display content on a device and dividing the content into a first displayable portion that is based on a size of a viewport of the device and a second displayable portion that is outside the viewport. The method also includes rendering and displaying the first displayable portion of content within the viewport, and selecting a subset of the second displayable portion of content for rendering off-screen based on a predetermined rule. Systems, graphical user interfaces, and machine-readable media are also provided.
