t:ACCELERATE Attribute | accelerate Property?deprecated)

This page documents a feature of HTML+TIME 1.0, which was released in Microsoft?Internet Explorer 5. We recommend that you migrate your content to the latest version of HTML+TIME, which implements the SMIL 2.0 Working Draft. See the Introduction to HTML+TIME overview for more information.

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

Syntax

XML <ELEMENT t:ACCELERATE = fRate... >
Scripting object.accelerate [ = fRate ]

XML	<ELEMENT t:ACCELERATE = fRate... >
Scripting	object.accelerate [ = fRate ]

Possible Values

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.
0 Default. 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.
