perfundo是一款纯CSS3 lightbox插件。它可以创建单张或多张图片的弹出lightbox层效果，也可以和js结合一起使用。

使用方法

在页面中引入perfundo-icons.css文件。

<link href="dist/perfundo.css" rel="stylesheet">
HTML结构

单张图片的HTML结构如下。

<div class="perfundo">
  <style>
  #perfundo-single:target:before{background-image:url(large.jpg);}
  </style>
  <a class="perfundo__link" href="#perfundo-single"> <img src="small.jpg"> </a>
  <div id="perfundo-single" class="perfundo__overlay"> 
    <a href="#perfundo-untarget" class="perfundo__close perfundo__control">Close</a> 
  </div>
</div>

多张图片的HTML结构如下：

<div class="perfundo">
  <style>#perfundo-img1:target:before{background-image:url(1.jpg);}</style>
  <a class="perfundo__link" href="#perfundo-img1">
    <img src="1.jpg">
  </a>
  <div id="perfundo-img1" class="perfundo__overlay">
    <a href="#perfundo-untarget" class="perfundo__close perfundo__control">Close</a>
    <a class="perfundo__next perfundo__control" href="#perfundo-img2">Next</a>
  </div>
</div>

<div class="perfundo">
  <style>#perfundo-img2:target:before{background-image:url(2.jpg);}</style>
  <a class="perfundo__link" href="#perfundo-img2">
    <img src="2.jpg">
  </a>
  <div id="perfundo-img2" class="perfundo__overlay">
    <a href="#perfundo-untarget" class="perfundo__close perfundo__control">Close</a>
    <a class="perfundo__next perfundo__control" href="#perfundo-img3">Next</a>
    <a class="perfundo__prev perfundo__control" href="#perfundo-img1">Prev</a>
  </div>
</div>

<div class="perfundo">
  <style>#perfundo-img3:target:before{background-image:url(3.jpg);}</style>
  <a class="perfundo__link" href="#perfundo-img3">
    <img src="3.jpg">
  </a>
  <div id="perfundo-img3" class="perfundo__overlay">
    <a href="#perfundo-untarget" class="perfundo__close perfundo__control">Close</a>
