HTML+TIME: Animation
This topic documents a feature of HTML+TIME 2.0, which is obsolete as of Windows Internet Explorer 9.
Introduction to HTML+TIME enables Web authors to animate content on the page by changing the value of particular attributes and properties over time. Without using script, you can animate an element's color; move an element along a specific path or between intervals; cause elements to appear or disappear over time or in response to events; or accelerate, reverse, or loop an animation. Although this animation functionality is available without script, most aspects of Introduction to HTML+TIME are also scriptable.
The following links provide access to the object model exposed by the time2 behavior.

Animating with keyTimes and keySplines
Using the keyTimes and keySplines attributes, you can divide an animation element's simple duration into multiple segments, speed up or slow down the animation at multiple rates during a single duration, and specify values for the animation to reach at particular points in its duration.
In HTML+TIME (Timed Interactive Multimedia Extensions) various types of media, animation, and other time elements can be played over a period of time. It is often desirable to be able to jump to any point on this time line. This process of jumping to different points on a time element's time line is called seeking.

Incorporate the time2 Behavior
This tutorial explains how to incorporate the time2 behavior in your Web pages so you can begin using timelines, multimedia, and animation with HTML elements.
Animation Elements and Objects

Events
Fires when the timeline starts on an element.

Fires when an element's media file causes any error.
Fires when the element loses synchronization with its associated timeline.
Fires when the timeline on an element pauses.
Fires when the timeline repeats on an element, beginning with the second iteration.
Fires when the timeline reaches the value of the BEGIN attribute or when the resetElement method is called on the element.
