我用Bootstrap找到了你的案子。这是最简单的解决方案：

注意：base64在SVG中是一个V字形。

仅限CSS和HTML的解决方案

它似乎与Chrome、Firefox和Internet Explorer 11兼容。但请留下您对其他网络浏览器的反馈。

正如Danield的回答所建议的那样，我将我的选择包装在一个div中（甚至两个div用于x浏览器兼容性），以获得预期的行为。

看见http://jsfiddle.net/bjap2/

HTML格式：

<div class="sort-options-wrapper">
    <div class="sort-options-wrapper-2">
        <select class="sort-options">
                <option value="choiceOne">choiceOne</option>
                <option value="choiceOne">choiceThree</option>
                <option value="choiceOne">choiceFour</option>
                <option value="choiceFiveLongTestPurpose">choiceFiveLongTestPurpose</option>
        </select>
    </div>
    <div class="search-select-arrow-down"></div>
</div>

注意两个div包装器。

还请注意，添加了额外的div以将箭头向下按钮放置在您喜欢的位置（绝对位置），这里我们将其放在左侧。

CSS

.sort-options-wrapper {
    display: inline-block;
    position: relative;
    border: 1px solid #83837F;
}

/* This second wrapper is needed for x-browser compatibility */
.sort-options-wrapper-2 {
    overflow: hidden;
}

select {
    margin-right: -19px; /* That's what is hiding the default-provided browser arrow */
    padding-left: 13px;
    margin-left: 0;
    border: none;
    background: none;

    /* margin-top & margin-bottom must be set since some
       browsers have default values for select elements */
    margin-bottom: 1px;
    margin-top: 1px;
}

select:focus {
    outline: none; /* Removing default browsers outline on focus */
}
.search-select-arrow-down {
    position: absolute;
    height: 10px;
    width: 12px;
    background: url(http://i.imgur.com/pHIYN06.png) scroll no-repeat 2px 0px;
    left: 1px;
    top: 5px;
}

从InternetExplorer10开始，您可以使用：：-ms-expand伪元素选择器来样式和隐藏下拉箭头元素。

select::-ms-expand {
    display:none;
    /* or visibility: hidden; to keep it's space/hitbox */
}

其余的样式应该与其他浏览器类似。

下面是Danield的jsfiddle的一个基本分支，它应用了对IE10的支持

您还可以向下拉列表中添加悬停样式。

选择｛position:relative；float:left；width:21.4%；height:34px；background:#f9f9e0；border:1px solid#41533f；padding:0px 10px 0px 10px；color:#41533f；margin:-10px 0px 0px 20px；backbackground:透明；字体大小：12px；-webkit外观：无；-moz外观：无(https://alt-fit.com/images/global/select-button.png)100%/15%无重复选择：悬停｛background:url(https://alt-fit.com/images/global/select-button.png)100%/15%无重复#fff；}<html><head></head><body><select name=“type”class=“select”><option style=“color:#41533f；”value=“select option”>选择选项</option><option value=“选项1”>选项1</option><option value=“option 2”>选项2</option><option value=“选项3”>选项3</option></选择></body></html>

select元素及其下拉功能很难设置样式。

Chris Heilmann的select元素的风格属性证实了Ryan Dohery对第一个答案的评论：

“select元素是操作系统，而不是浏览器chrome。因此风格不可靠，尝试也不一定有意义无论如何"

博客文章HowtoCSS表单下拉样式没有JavaScript适合我，但在Opera中失败了：

选择{边框：0无；颜色：#FFFFFF；背景：透明；字体大小：20px；字号：粗体；填充：2px 10px；宽度：378px；*宽度：350px；*背景：#58B14C；}#主要选举{溢出：隐藏；宽度：350px；-moz边框半径：9px 9px 9px 9px；-webkit边框半径：9px 9px 9px 9px；边框半径：9px 9px 9px 9px；方框阴影：1px 1px 11px#3330033；background:url（“arrow.gif”）无重复滚动319px 5px#58B14C；}<div id=“mainselection”><选择><option>选择选项</option><option>选项1</option><option>选项2</option></选择></div>
