我正在尝试用我自己的照片替换选择的箭头。我包括选择在一个div与相同的大小，我设置的背景选择为透明，我包括一个图片(与箭头大小相同)在div的右上角作为背景。
它只适用于Chrome浏览器。
我如何让它在Firefox和IE9中工作，我得到了这个:
.styled-select {
width: 100px;
height: 17px;
overflow: hidden;
overflow: -moz-hidden-unscrollable;
background: url(images/downarrow_blue.png) no-repeat right white;
border: 2px double red;
display: inline-block;
position: relative;
}
.styled-select select {
background: transparent;
-webkit-appearance: none;
width: 100px;
font-size: 11px;
border: 0;
height: 17px;
position: absolute;
left: 0;
top: 0;
}
body {
background-color: #333333;
color: #FFFFFF;
}
.block label {
color: white;
}
<HTML>
<HEAD>
</HEAD>
<BODY>
<p/>
<form action="/prepareUpdateCategoryList.do?forwardto=search">
<fieldset class="block" id="searchBlock">
<p>
<label style="width:80px">Class</label>
<div class="styled-select">
<select property="voucherCategoryClass">
<option value="0">Select </option>
<option value="7382">steam </option>
</select>
</div>
</p>
</fieldset>
</form>
</BODY>
</HTML>
我想澄清一件之前没人提到过的事。
首先获取svg图像或图标
在那里，你会得到一些xml代码，如这些<svg width="24" height="25" viewBox="0 0 24 25" fill="none" xmlns="http://www.w3.org/2000/svg"> <path d="M4 10.127L12 18.127L20 10.127H4Z" fill="#8E8E93"/> </svg>试着找到它。
然后在这段代码后面加上data:image/svg+xml;utf8，
替换填充颜色fill="#8E8E93"到this fill="%238E8E93"如果你想添加十六进制颜色，你应该将#改为%23
下面是html代码:
<fieldset>
<label for="editName">Country</label>
<select class="ra-select">
<option value="bangladesh" selected>Bangladesh</option>
<option value="saudi arabia">Saudi Arabia</option>
<option value="us">Uinited State Of America</option>
<option value="india">India</option>
</select>
</fieldset>
下面是css代码:
.ra-select {
width: 30%;
padding: 10px;
/* Replace Default styling (arrow) */
appearance: none;
-webkit-appearance: none;
-moz-appearance: none;
background-image: url('data:image/svg+xml;utf8,<svg width="24" height="25" viewBox="0 0 24 25" fill="none" xmlns="http://www.w3.org/2000/svg"><path d="M4 10.127L12 18.127L20 10.127H4Z" fill="%238E8E93"/></svg>');
background-repeat: no-repeat;
background-position-y: 50%;
background-position-x: 98%;
}
.ra-select:focus,
.ra-select:hover {
outline: none;
border: 1px solid #bbb;
}
.ra-select option {
background-color: #fff;
}
这里有几个例子
它是基于这个答案，但我添加了一个列表，以使设计更加简洁
select.moreMinimal {
background-color: inherit;
display: inline-block;
font: inherit;
padding: 0 2.2em 0 1em;
margin: 0;
cursor: pointer;
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;
-webkit-appearance: none;
-moz-appearance: none;
}
select.moreMinimal {
background-image:
linear-gradient(45deg, transparent 50%, gray 50%),
linear-gradient(135deg, gray 50%, transparent 50%);
background-position:
calc(100% - 20px),
calc(100% - 15px);
background-size:
5px 5px,
5px 5px;
background-repeat: no-repeat;
}
//TODO: Probably shouldn't be focus, cause when you click it again it's still green
select.moreMinimal:focus {
background-image:
linear-gradient(45deg, green 50%, transparent 50%),
linear-gradient(135deg, transparent 50%, green 50%);
background-position:
calc(100% - 15px),
calc(100% - 20px);
background-size:
5px 5px,
5px 5px;
background-repeat: no-repeat;
border-color: green;
outline: 0;
}
