Pre- and post-animation state: animation-fill-mode, step 1

In the previous examples, elements went back to the original state after being animated. However, there is a property that will define whether an animation effect will remain visible after the playback is over. It’s called animation-fill-mode. When the property is set to forwards, the element will keep its state after the animation is over.

Let’s see how this property works using an example: we will apply the same animation to two identical objects, then change the value of the animation-fill-mode property and see what happens.

    1. Assign the reaction animation to both .reagent chemicals with a duration of 3s and a playback delay of 2s,
    2. and then make the experimental chemical .experimental-reagent save its state after animation.
