CSS：在select元素下面的内容导致click不起作用

I have this (simplified) css for the select element to get rid of the browser-specific appearance

我有这个(简化的)CSS的select元素摆脱浏览器特定的外观

.select{
    display:inline-block;
    position:relative;
}
.select:after{
    position:absolute;
    bottom:0;right:0;
    content:'\2193'; 
}
select{
    appearance:none; (-moz and -webkit too)
    width:100%;
    height:100%;
}

body{
    background:#eef;
    font-family:sans-serif;
}
.select{
    display:inline-block;
    background-color:#fff;
    border-radius:.5em;
    border:.1rem solid #000;
    color:#013;
    width:8em;
    height:1.5em;
    vertical-align:middle;
    position:relative;
}
.select:after{
	position:absolute;
	bottom:.15em;top:.15em;right:.5rem;
	content:'\2193'; 
}
select{
    -webkit-appearance:none;
   -moz-appearance:none;
   	appearance:none;
    font:inherit;
    border:none;
    background-color:transparent;
    color:inherit;
    width:100%;
    height:100%;
    padding:0 .5em;
}

<span class="select">
    <select>
        <option>A</option>
        <option>B</option>
    </select>
</span>

It looks good, aside from Firefox still showing the arrow (as described Firefox 30.0 - -moz-appearance: none not working)

看起来不错,除了Firefox还显示箭头(如Firefox 30.0所述 - -moz-appearance:none not working)

The only technical problem is that when I click on the select element, it shows the option elements, but if I click directly on the arrow, it does not.

唯一的技术问题是,当我单击select元素时,它会显示选项元素,但如果我直接单击箭头,则不会。

Is there a way to avoid this?

有没有办法避免这种情况?

The simplest CSS solution would be to add pointer-events: none to the pseudo element. In doing so, you can click through the element because mouse events are removed.

最简单的CSS解决方案是将指针事件:none添加到伪元素中。这样,您可以单击该元素,因为鼠标事件已被删除。

Updated Example

.select:after {
    position:absolute;
    bottom:.15em;
    top:.15em;
    right:.5rem;
    content:'\2193';
    pointer-events: none;
}

^{(Just take browser support for the property into consideration.)}

(只需考虑浏览器对该属性的支持。)
