首先看一下效果图;

css3 menu 手机菜单3

效果1，主要是 scale(0) -->scale(1px);opacity:0;—>opacity: 1; 然后递归延迟 怕麻烦也可以自己写个for循环

.five b {transform: scale(0); opacity: 0;}

.five:hover b {transform: scale(1);  opacity: 1; transition: all 0.4s cubic-bezier(0.175, 0.885, 0.32, 1.275);}

.five i {transform: scale(0); opacity: 0;}

.five:hover i {transform: scale(1);  opacity: 1; transition: all 0.4s cubic-bezier(0.175, 0.885, 0.32, 1.275);}

效果2，主要是 scale(1.5) -->scale(1px);opacity:0;—>opacity: 1;自己弄个cubic-bezier(0.175, 0.885, 0.32, 1.275)；类似弹簧

.six a {transform: scale(1.5); opacity: 0;}

.six:hover a {transform: scale(1);  opacity: 1; transition: all 0.4s cubic-bezier(0.175, 0.885, 0.32, 1.275);}
