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>
我已经提到了这篇文章，它像魅力一样工作，除了它没有隐藏在IE浏览器中的箭头。
但是添加以下会隐藏IE中的箭头:
&: -ms-expand {
显示:没有;
}
完整解决方案(sass)
$select-border-color: #ccc;
$select-focus-color: green;
select {
cursor: pointer;
/* styling */
background-color: white;
border: 1px solid $select-border-color;
border-radius: 4px;
display: inline-block;
font: inherit;
line-height: 1.5em;
padding: 0.5em 3.5em 0.5em 1em;
/* reset */
margin: 0;
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;
-webkit-appearance: none;
-moz-appearance: none;
background-image: linear-gradient(45deg, transparent 50%, $select-border-color 50%),
linear-gradient(135deg, $select-border-color 50%, transparent 50%),
linear-gradient(to right, $select-border-color, $select-border-color);
background-position: calc(100% - 20px) calc(1em + 2px),
calc(100% - 15px) calc(1em + 2px), calc(100% - 2.5em) 0.5em;
background-size: 5px 5px, 5px 5px, 1px 1.5em;
background-repeat: no-repeat;
/* Very imp: hide arrow in IE */
&::-ms-expand {
display: none;
}
&:-moz-focusring {
color: transparent;
text-shadow: none;
}
&:focus {
background-image: linear-gradient(45deg, $select-focus-color 50%, transparent 50%),
linear-gradient(135deg, transparent 50%, $select-focus-color 50%), linear-gradient(to right, $select-focus-color, $select-focus-color);
background-position: calc(100% - 15px) 1em, calc(100% - 20px) 1em, calc(100% - 2.5em) 0.5em;
background-size: 5px 5px, 5px 5px, 1px 1.5em;
background-repeat: no-repeat;
border-color: $select-focus-color;
outline: 0;
}
}
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;
}
