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,首先是HTML代码,非常简单:
 
复制代码
<div id="gal">
  <nav class="galnav">
    <ul>
        <li><input type="radio" name="btn" value="one" checked="checked" />

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:
 
复制代码
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:0;
  z-index:9;
}
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:7;
  -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;
}
