Techniques for coordinating movements of various objects in an electronic document are disclosed. A first-type object remains stationary so that it becomes outside a content boundary of the electronic document, as the content boundary is pulled inside an edge of a window displaying the electronic document. A second-type object remains stationary until the content boundary reaches the edge of the window and then moves along with the scrolled electronic document as the content boundary is pulled inside the edge of the window. A third-type object and a fourth-type object may show different movement behaviors.

Coordination of static backgrounds and rubberbanding

Systems and methods for hardware accelerated presentation of web pages on mobile computing devices are presented. A plurality of web pages may be received by a computing device capable of processing and displaying web pages using layout engines, hardware accelerated graphics application programming interfaces (APIs). Upon receipt of the web pages, the web pages may be divided into a plurality of rendering layers, based upon stylesheets of the web pages. An algorithm walks through rendering layers so as to select a plurality of layers that may receive compositing layers so as to take advantage of hardware acceleration when rendered. The web pages may be subsequently presented on a display of the mobile computing devices using remaining rendering layers and compositing layers. In this manner, visual representation of web content remains intact even when content which may not have been originally designed for use with layout engine may be displayed.

Acceleration of rendering of web-based content

Some embodiments relate to providing an improved progress indicator in a graphical user interface. In addition to conveying a completion status of a task to a user, an improved progress indicator in some embodiments can convey additional information about the task to the user. For example, some embodiments can display a visual cue when a triviality threshold indicating that the task is 'substantially complete' is met.

Embodiments of the present invention provide a way to perform transforms and animations using Cascading Style Sheets (CSS). CSS may be used to define colors, fonts, layout, and other aspects of document presentation, such as for a webpage. Embodiments of the present invention provide CSS properties for transforms and animations of document content. New CSS properties for transforms allow for rotation, translation, scaling, skewing, perspective, origin, and the like. CSS properties are also provided for animating document content, such as movement, transitions, and the like.
