A keyframe object or null. If set to null, the keyframes are replaced with a sequence of empty keyframes.

Exceptions

Exception Explanation
TypeError One or more of the frames were not of the correct type of object, the keyframes were not loosely sorted by offset, or a keyframe existed with an offset of less than 0 or more than 1.

Note: If the keyframes cannot be processed or are malformed, the KeyframeEffect's keyframes are not modified.

[
  { color: 'blue' },
    { color: 'green', left: '10px' }
  ]
