Summary

CSS animations have evolved with the introduction of the linear() easing function, providing greater control over timing and enabling complex animations such as bouncy and elastic effects. Unlike the traditional linear keyword that animates at a constant speed, the linear() function allows for compound movements by accepting multiple points as inputs, creating intricate transitions with straight-line segments. This advancement contrasts with previous methods that relied heavily on JavaScript or cumbersome @keyframes for complex animations. The article explains the use of easing functions, which dictate the rate of change in animations, and highlights other CSS functions like steps() and cubic-bezier() for defining custom easings. It also introduces resources for generating or utilizing pre-made linear() easings, such as the GSAP JavaScript library and Open Props CSS library. The article concludes by emphasizing the importance of accessibility through the prefers-reduced-motion media query, ensuring animations cater to users sensitive to motion.
