本文给大家讲h5、select下拉框右边加图标，深度美化页面增进用户体验效果
1.那么我们先来看一下效果吧！
2.再看看h5的结构：
<div id="login-div">
<div class="select-wrapper">
<select id="selector1">
<option value="" disabled selected>请选择系统：</option>
<option value="1">微信-苹果</option>
<option value="2">微信-安卓</option>
</select>
<img src="ossweb-img/arrow.png" alt="" class="arrow" />
</div>
<div class="select-wrapper">
<select id="selector2">
<option value="" disabled selected>请选择渠道：</option>
<option value="1">渠道1</option>
<option value="2">渠道2</option>
</select>
<img src="ossweb-img/arrow.png" alt="" class="arrow" />
</div>
<div class="select-wrapper">
<select id="selector3">
<option value="" disabled selected>请选择大区：</option>
<option value="1">大区1</option>
<option value="2">大区2</option>
</select>
<img src="ossweb-img/arrow.png" alt="" class="arrow" />
</div>
<div class="select-wrapper">
<select id="selector4">
<option value="" disabled selected>请选择角色：</option>
<option value="1">角色1</option>
<option value="2">角色2</option>
</select>
<img src="ossweb-img/arrow.png" alt="" class="arrow" />
</div>
<p id="notice">单个帐号只能领取一次奖励</p>
<img src="ossweb-img/comfire1.png" alt="" id="comfire1"/>
</div>3.样式部分是用了sass进行控制的，如果不会sass也可以换成css。没有什么特别的运算需要转化，所以换成css也简单
@function REM($n){
@return $n/$REM*1rem;
}
#login-div{
background: url(../ossweb-img/kuang1.png)0 0 no-repeat;
