Property values
Type: Integer
A floating-point number that specifies a value between 0 and 1, which represents the portion of the timeline over which the acceleration is applied. The timeline refers to the timeline associated with a particular HTML element, such as a div or a span, instead of the timeline associated with the entire document.
Remarks
If the REPEATCOUNT attribute or the REPEATDUR attribute is set on an element, the acceleration occurs each time the element repeats.
The 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.
The sum of the values for the ACCELERATE attribute and the DECELERATE attribute must not exceed 1. If the individual values of the ACCELERATE attribute and the DECELERATE attribute are between 0 and 1, and the sum of the attributes is greater than 1; then both attributes are ignored, and the timed element behaves as if neither attribute was specified.
This property is also called "ease-in" in some systems.
Examples
This example uses the accelerate element to demonstrate an accelerated element timeline.
