sets or retrieves a value that applies an acceleration to the element's local timeline.

dhtml语法

xml<ELEMENT t:ACCELERATE = fRate... >
Scriptingobject.accelerate [ = fRate ]

DHTML可能的值

fRate Floating-point number that specifies a value between 0 and 1 representing 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), rather than the global timeline associated with the entire document.
0Default. Acceleration is not applied to the element's timeline.

The property is read/write. The property has a default value of 0.

Remarks

If the t:repeat or t:repeatdur attribute is set on an element, the acceleration occurs each time the element repeats.

the t:accelerate attribute is especially well suited to animation content and behaviors. setting this attribute to a nonzero value does not affect the duration of the timeline, but it could 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 1. this property is also commonly known as "ease-in" in some systems.
