今天看到一个纯css模态框，觉得是很牛呀
看了下用了target伪类，
一直不知道有这么神奇的伪类
。。
用法是这样的，给模态框一个id，
<div id="pop" class="overlay">
然后通过锚链接的方法
<a class="button" href="#pop">Click!</a>
点击之后，伪类的css就能发生作用了
.overlay:target {
visibility: visible;
opacity: 1;
}
.overlay:target > .modal {
transform: translateY(30%) scale(0.9);
transition-timing-function: cubic-bezier(0.8, 0, 0, 1.5);
opacity: 1;
}
顺便把别人的源码发一下
