DECELERATE Attribute | decelerate Property

  • Artigo

This topic documents a feature of HTML+TIME 2.0, which is obsolete as of Windows Internet Explorer 9.

Sets or gets a value that applies a deceleration to the end of a simple duration.

Syntax

HTML <ELEMENT DECELERATE = fRate... >
Scripting [ fRate = ] object.decelerate

Possible Values

fRate A floating-point number that specifies a value between 0 and 1, which represents the portion of the timeline over which the deceleration is applied. The timeline refers to that timeline associated with a particular HTML element, such as a div or a span, instead of the timeline associated with the entire document.
0
Default. Deceleration is not applied to the element timeline.

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

Remarks

The simple duration is the segment of time from when the element begins playing until it completes one forward cycle of its behavior, excluding repetitions.

If the REPEATCOUNT attribute or the REPEATDUR attribute is set on an element, the deceleration occurs each time the element repeats.

The DECELERATE 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 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-out" in some systems.

Example

This example uses the decelerate element to display a decelerated timeline.
