CSS animations

CSS animations are a way to create dynamic effects on web pages using styles defined in CSS (Cascading Style Sheets). They allow elements to change smoothly over time, making content more engaging. For example, you can animate an object's size, color, or position with simple code that specifies the starting and ending states. By using keyframes, you define the stages of the animation, and CSS handles the transitions automatically. This enhances user experience, adds visual interest, and can be used for subtle effects or bold movements, all while maintaining performance and responsiveness on various devices.
