CSS Reference Guide: Transitions

The CSS transition property is a shorthand tool that facilitates smooth animations in CSS by allowing properties to change gradually over a set duration, making these changes perceptible to the human eye. It includes several components: transition-property, transition-duration, transition-timing-function, and transition-delay, each controlling different aspects of the animation. Transition-property specifies which CSS properties will undergo transition, while transition-duration sets the length of the animation. The transition-timing-function determines the pace of the animation, offering options like ease, linear, ease-in, and ease-out, which control how the transition speed varies over time. Transition-delay specifies the time before the transition starts once a property has changed. Examples illustrate how these properties can be used to animate changes in width and background-color when elements are hovered over, with transitions triggered by pseudo-classes like :hover. The transition property can handle multiple transitions simultaneously, and its flexibility allows for various animations that enhance user interactions by making them more intuitive and visually appealing.
