html - CSS 选择框箭头样式

Question

我想从选择框中删除默认箭头并使用自定义图标。从之前关于 SO 的回答中，我发现这是不可能的(让它与主流浏览器一起工作)。唯一的可能性是将 select 包裹在一个 div 中，并将其宽度设置为大于 div 宽度并设置溢出:隐藏。我正在尝试关注，但它不起作用。我做错了什么？

.selectParent {
  width: 80px;
  overflow: hidden;
}

.selectParent select {
  width: 100px;
  -webkit-appearance: none;
  -moz-appearance: none;
  appearance: none;
  padding: 2px 30px 2px 2px;
  border: none;
  background: transparent url("http://cdn1.iconfinder.com/data/icons/cc_mono_icon_set/blacks/16x16/br_down.png") no-repeat right center;
}

<div class="selectParent">
  <select>
    <option value="1">Option 1</option>
    <option value="2">Option 2</option>           
   </select>
</div>

请按照以下方式操作:

.selectParent {
	width:120px;
	overflow:hidden;   
}
.selectParent select { 
	display: block;
	width: 100%;
	padding: 2px 25px 2px 2px; 
	border: none; 
	background: url("http://cdn1.iconfinder.com/data/icons/cc_mono_icon_set/blacks/16x16/br_down.png") right center no-repeat; 
	appearance: none; 
	-webkit-appearance: none;
	-moz-appearance: none; 
}
.selectParent.left select {
	direction: rtl;
	padding: 2px 2px 2px 25px;
	background-position: left center;
}
/* for IE and Edge */ 
select::-ms-expand { 
	display: none; 
}

<div class="selectParent">
  <select>
    <option value="1">Option 1</option>
    <option value="2">Option 2</option>           
   </select>
</div>
<br />
<div class="selectParent left">
  <select>
    <option value="1">Option 1</option>
    <option value="2">Option 2</option>           
   </select>
</div>
