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;
}
}
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;
}
