In modern web development, animation plays a crucial role in enhancing user experience, making websites more engaging and interactive. CSS and JavaScript animation libraries provide a convenient and efficient way to add smooth, dynamic animations to web pages without requiring complex code.

While CSS is great for simple animations, JavaScript animation libraries offer more flexibility and control over complex animations. JavaScript allows developers to create interactive, customizable, and even physics-based animations, making it a go-to choice for dynamic web applications.
