Abstract

An electronic device receives touch input signals associated with a respective region of a web page. The respective region of the web page is associated with a plurality of event handlers or event listeners including an event handler or listener for a touch event and an event handler or listener for a gesture event. In response to receiving the touch input signals, the device sends a gesture event to the web page. The gesture event corresponds to a combination of two or more touch events, and the two or more touch events correspond to the touch input signals. The device dynamically rotates an element associated with the respective region of the web page with the event handler or listener for the gesture event based on a rotation value associated with the gesture event, and sends the touch events to the web page for processing, distinct from the dynamically rotating.
