Transitions and Animations in CSS Changing Values with CSS

This practical book shows you how CSS transitions and animations provide a way to control how a property changes from one value to the next over time. You can make the property value change gradually, creating pleasant and hopefully unobtrusive effects. CSS transitions let you decide which properties to animate, how long to wait before the animation starts, how long the transition should take, and how the transition will proceed—all of which are customizable.
