CSS animations lets you run animations smoothly, even under moderate system load. Simple animations can often perform poorly in JavaScript (unless they’re well made). The rendering engine can use frame-skipping and other techniques to keep the performance as smooth as possible and letting the browser control the animation sequence lets the browser optimize performance and efficiency by, for example, reducing the update frequency of animations running in tabs that aren’t currently visible.

In this roundup, we would like to present our audience 18 Best CSS Effect Libraries that enable you to create stunning animations to make your designs more attractive and eye catching. These CSS effect libraries help you to create interactive designs without the need of Flash, Silverlight or After Effects. We hope you will find the list handy and useful, we would love to hear from you, please give us your feedback by posting comment below. Enjoy !!
