Sets or gets a value that applies an acceleration to the element's local timeline.
XML <ELEMENT t:ACCELERATE = fRate... > Scripting [ fRate = ] object.accelerate
fRate A floating-point number that specifies a value between 0 and 1 which representsg the portion of the local timeline over which the acceleration is applied. The local timeline refers to the timeline associated with a particular HTML element, such as a div or span, instead of the global timeline associated with the entire document.
- Default. Acceleration is not applied to the element timeline.
The property is read/write. The property has a default value of 0.
The t:ACCELERATE attribute is well-suited to animation content and behaviors. Setting this attribute to a nonzero value does not affect the duration of the timeline, but it might change the effective play speed of the local timeline. The sum of the values for the t:ACCELERATE and t:DECELERATE attributes must not exceed one. This property is also commonly known as "ease-in" in some systems.
