Pre- and post-animation state: animation-fill-mode, step 3

Another value of the animation-fill-mode property is backwards. This value defines the state of an element before the start of an animation.

If an element has an animation assigned to it with a delay and animation-fill-mode: backwards, the styles described in the first keyframe from or 0% will be applied at once, before the animation is played.

Let’s consider a specific example.

    1. Assign a power animation with a duration of 2s and a playback delay of 2s to the battery charge .energy-fill,
    2. then make the charge in the experimental battery .mega-energy-fill display its state before the animation starts.
