Animation control methods and systems. In one embodiment, a method to control animations includes receiving data representing content of a page (e.g. a web page), detecting, from the data, whether the page includes animated content, determining whether to halt execution of the detected animated content, and halting execution of the animated content if a determination to halt was made. In one implementation, the content can be configured into a document object model (DOM) and decisions to halt or not to halt can be made on a node-by-node basis within the DOM. In one implementation, the animated content can be allowed to execute for a shortened duration (e.g. in order to allow a user to see it) and then is halted.
