<body>
<div>设计思路:
1、用ul和li标签，ul用相对定位，li标签用绝对定位
2、设置input标签的id，在通过label标签的for属性实现input的checked选中,input选中后再通过元素选择器实现轮播图的切换和label样式的改变
</div>
<ul>
<input id="check1" type="radio" name="control" checked/>
<input id="check2" type="radio" name="control"/>
<input id="check3" type="radio" name="control"/>
<li class="slide">1</li>
<li class="slide">2</li>
<li class="slide">3</li>
<div class="_footer">
<label for="check1"></label>
<label for="check2"></label>
<label for="check3"></label>
</div>
</ul>
</body>
