前言
在数字时代，网页不再是静态的画面，而是充满活力和动感的空间。CSS3的过渡与动画技术就像是一场魔法表演，能够赋予网页以生命。本文将引领你进入这个奇妙的世界，解锁CSS3过渡与动画的神奇效果。
过渡
过渡的基本使用 transition
transition过渡属性时css3浓墨重彩的特性，过渡可以为一个元素在不同样式之间变化自动添加“补间动画”
兼容性
过渡从IE10开始兼容，移动端兼容良好
曾几何时，网页上的动画特效基本都是由JavaScript定时器实现的，现在逐步改为使用css3过渡
优点：动画更细腻，内存开销小
transition属性基本使用
注意，这里的1s、0s里的s不能省略
哪些属性可以参与过渡
- 所有数值类型的属性，都可以参与过渡，比如width.height、left、top、border-radius
- 背景颜色和文字颜色都可以被过渡
- 所有变形（包括2D和3D）都能被过渡
all
如果要所有属性都参与过渡，可以写all
transition:all 1s linear 0s;
注意：不要滥用，会引发效益问题
过渡的四个小属性
过渡的缓动效果
transition 的第三个参数就是缓动参数，也是变化速度曲线
常用缓动参数
贝塞尔曲线
网站https://cubic-bezier.com/可以生成贝塞尔曲线，可以自定义动画缓动参数
transition:width 1s cubic-bezier(.44,-0.62,.62,1.59) 0s;

动画
动画的定义和调用
可以使用@keyframes来定义动画，keyframes表示“关键帧”，在项目上线前，要补上@-webkit-这样的私有前缀
定义动画之后，就可以使用animation属性调用动画
动画的执行次数
第五个参数就是动画的执行次数
animation:r 1s linear 0s 3; //3表示次数
如果想永远执行可以写infinite
animation:r 1s linear 0s infinite; //表示一直执行动画
如果想让动画的第2、4、6……偶数次自动逆向执行，那么要加上alternate参数即可
animation:r 1s linear 0s infinite alternate;
如果想让动画停止在最后结束状态，那么要加上forwards
animation:r 1s linear 0s forwards;
