Usage of the 'animation-fill-mode' Property

This property is handy when you want an element to retain the style values from either the start or end keyframes of an animation rather than reverting to its initial styles after the animation completes. It's also handy for setting up an element's style before the start of an animation.

Property Values of the 'animation-fill-mode' Property

• None: The default value. The animation does not apply any styles to the target before or after it executes. Once the animation completes, the element will revert to its initial style.
• Forwards: The element will retain the style values set by the last keyframe (considering the animation's direction). This means that after the animation ends, the element keeps the styles from the end of the animation.
• Backwards: The element will receive the style values from the first keyframe as soon as the animation is applied before it officially begins. This is useful for setting an initial state for entering animations.
• Both: Applies the rules for both forwards and backward. The element maintains the style state from the first keyframe before the animation starts and retains the last keyframe's styles after the animation ends.
