CSS animations are a powerful tool that can add visual interest and interactivity to web pages. One key property in managing CSS animations is the animation-play-state property, which allows developers to control whether an animation is running or paused. This article explores the animation-play-state property in detail, providing insights and examples for beginners.
I. Introduction
A. Overview of CSS animations
CSS animations allow you to animate transitions and provide more engaging user experiences. They are defined using the keyframes or transition properties in CSS. Animation can bring life to web elements, making them more appealing and interactive to users.
B. Importance of animation play state

animation-play-state: value;
}
III. Property Values

animation: move 3s linear infinite;
animation-play-state: running;
}
@keyframes move {
