<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>
