纯CSS3美化radio和checkbox

</span>

当然，尽管说不能兼容，可是对于为什么不能兼容还是须要解释一下的，其关键在于这么个选择器的问题：input[type=radio]:before。:beofre这个伪类选择器在主流浏览器中能够在P,span,div等标签插入一些式样，可是在input中就不行，索性chrome支持这一特性，而本实例也正是环绕着一特性进行开发。

其它不多说，直接上代码和截图。

HTML代码：

<label for="test1">Test for test1 </label>
        <input class="radio" type="radio" ID="test1" name="test" value="test1"/>
        <label for="test2">Test for test2 </label>
        <input class="radio" type="radio" ID="test2" name="test" value="test2"/>

        <br>
        <br>
        <br>
        <label for="check1">check1</label>
        <input id="check1" name="check"  value="check1" type="checkbox" class="checkbox"/>
        <label for="check2">check2</label>
        <input id="check2" name="check" value="check2" type="checkbox" class="checkbox"/>
        <label for="check3">check3</label>
        <input id="check3" name="check" value="check3" type="checkbox" class="checkbox"/>
        <label for="check4">check4</label>
        <input id="check4" name="check" value="check4" type="checkbox" class="checkbox"/>
