之前我们经常会看到很多利用jQuery实现的焦点图插件，种类太多了，今天我想给大家分享一款利用纯CSS3实现的图片滑块应用，完全是利用CSS3的相关特性，没有使用JS，个人觉得还是挺不错的，先来看看效果图：
看上去挺不错的吧，简洁、清新、大气。
当然我们也可以在这里查看DEMO演示。
接下来我们一起来分析一下源码，首先是HTML代码，非常简单：
<div id="gal">
<nav class="galnav">
<ul>
<li><input type="radio" name="btn" value="one" checked="checked" />
<label for="btn"></label>
<figure>
<img src="data:images/01_Fabio_Basile.jpg" />
<figcaption>
<h4>Fabio Basile</h4>
<nav role='navigation'>

这些HTML代码只是构造了几张图片，等一下可以切换。另外，每张图片都放置一个radio，这个radio来充当切换按钮。
接下来就是CSS代码了:

这个CSS代码相对比较复杂，重点在这个地方：
利用label重写radio的样式，但是又能完成点击label就像点击radio一样的效果，核心代码如下：
input[type="radio"], input[type="radio"] + label {
position:absolute;
bottom:15px;
display:block;
width:20px;
height:20px;
-webkit-border-radius:50%;
-moz-border-radius:50%;
border-radius:50%;
cursor:pointer;
}
input[type="radio"] {
opacity:;
z-index:;
}
input[value="one"], input[value="one"] + label {left:20px;}
input[value="two"], input[value="two"] + label {left:128px;}
input[value="three"], input[value="three"] + label {left:236px;}
input[value="four"], input[value="four"] + label {left:344px;}
input[value="five"], input[value="five"] + label {left:452px;}
input[value="six"], input[value="six"] + label {right:20px;}
input[type="radio"] + label {
background:rgba(255,255,255,0.35);
z-index:;
-webkit-box-shadow:0px 0px 0px 0px rgba(255,255,255,0.15);
-moz-box-shadow:0px 0px 0px 0px rgba(255,255,255,0.15);
box-shadow:0px 0px 0px 0px rgba(255,255,255,0.15);
-webkit-transition:all .3s;
-moz-transition:all .3s;
-o-transition:all .3s;
transition:all .3s;
}
