Style animationFillMode Property

❮ Previous ❮ Style Object Reference Next ❯

Example

Changing the animationFillMode property of a <div> element:

document.getElementById("myDIV").style.animationFillMode = "forwards";

Description

The animationFillMode property specifies what styles will apply for the element when the animation is not playing (when it is finished, or when it has a "delay").

By default, CSS animations will not affect the element you are animating until the first keyframe is "played", and then stops affecting it once the last keyframe has completed. The animationFillMode property can override this behavior.

Syntax

Return the animationFillMode property:

object.style.animationFillMode

Set the animationFillMode property:

Property Values

Value	Description

backwards	The animation will apply the property values defined in the keyframe that will start the first iteration of the animation, during the period defined by animation-delay. These are either the values of the from keyframe (when animation-direction is "normal" or "alternate") or those of the to keyframe (when animationDirection is "reverse" or "alternate-reverse")
both	The animation will follow the rules for both forwards and backwards. That is, it will extend the animation properties in both directions
