Methods and systems for declarative animation timelines are disclosed. In some embodiments, a method includes generating a declarative timeline data structure, creating an animation of an image along the timeline, and adding a declarative command corresponding to the animation into the declarative data structure. The method also includes, in response to a request to render the animation, generating a run-time command corresponding to the declarative command and executing the run-time command. In other embodiments, a method includes receiving a request to render an animation, wherein the animation includes a declarative timeline data structure having a plurality of commands, parsing the plurality of commands, passing each of the parsed plurality of commands to an animation function, receiving a plurality of run-time commands in response to said passing, and causing a rendering the animation by causing an execution of the plurality of run-time commands.
