ICSSKeyframeRule class

The CSSKeyframeRule interface represents the style rule for a single key.

The ICSSKeyframeRule type exposes the following members:

Property	Description
key_text	This attribute represents the keyframe selector as a comma-separated list of percentage values. The ‘from’ and ‘to’ keywords map to ‘0%’ and ‘100%’, respectively.
style	This attribute represents the style associated with this keyframe.
type	The type of the rule, as defined above. The expectation is that binding-specific casting methods can be used to cast down from an instance of the CSSRule interface to the specific derived interface implied by the type.
css_text	The parsable textual representation of the rule. This reflects the current state of the rule and not its initial value.
parent_style_sheet	The style sheet that contains this rule.
parent_rule	If this rule is contained inside another rule (e.g. a style rule inside an @media block), this is the containing rule. If this rule is not nested inside any other rules, this returns null.
