input选择框样式修改与自定义

html自带的选择框样式不好看，并且在ios设备上丑的罚款。所以一般都是自定义样式；

原理：将原来默认的input选择框隐藏，然后控制label的:before与:after,配合矢量图标或者图片来实现选中效果。

由于时间原因，只做了个一种样式。想要其他样式的话改改就行了。想看更详细的给大家推荐个网址可以详细看看：http://www.jq22.com/yanshi11319

效果：

　　

 这些样式大小、颜色、图标都是可以改的啦。有时间要做一套出来，可以直接用的啦。建议用图片做，如果用矢量图标的话效果虽然好，但是要引入图标库并且有点小问题。

html代码：

<link rel="stylesheet" href="http://at.alicdn.com/t/font_bo8heq56fci60f6r.css">
<p class="checkbox"><input id="agree_check" type="checkbox"><label for="agree_check">我已阅读并同意<a href="user_agreement.html" target="_blank"><span class="blue">《软件使用协议》</span></a></label></p>
<p class="tc mt10"><button class="btn_submit" @click="_submit()">立即分享</button></p>


<div class="radiobox">
    <input type="radio" id="nan" name="sex" value="1" v-model="sex" /><label for="nan">男</label>
</div>
<div class="radiobox">
    <input type="radio" id="nv" name="sex" value="2" v-model="sex" /><label for="nv">女</label>
</div>
