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>

下面是一个优雅的修复,它使用span来显示值。

布局是这样的:

<div class="selectDiv">
   <span class="selectDefault"></span>
   <select name="txtCountry" class="selectBox">
      <option class="defualt-text">-- Select Country --</option>
      <option value="1">Abkhazia</option>
      <option value="2">Afghanistan</option>
   </select>
</div>

下面是替换箭头的最优雅的方法:

select {
  padding: 15px 5px 15px 15px;
  border: none;
  font-family: Verdana;
  font-weight: bold;
  background-color: DodgerBlue;
  color: white;
  outline: none;
  min-width: 150px;
  cursor: pointer;

  /*Remove decorations to replace arrow with custom arrow */   
  appearance: none;
  -moz-appearance: none;
  -webkit-appearance: none;  
  &::-ms-expand { display: none };  
}
.custom-select:after {
    /* Here we add font taken from libre office to content */
    content: "▼";
    position: absolute;
    top: 4;
    /* Here we need to calculate fonts place so that if select box width changes the custom button font will be always at same place */
    left: calc(100% - 30px);
    font-size: 80%;
    padding: 12px 7px;
    background-color: DodgerBlue;
    color: white;
    pointer-events: none;
}

只使用一个类:

select {
    width: 268px;
    padding: 5px;
    font-size: 16px;
    line-height: 1;
    border: 0;
    border-radius: 5px;
    height: 34px;
    background: url(http://cdn1.iconfinder.com/data/icons/cc_mono_icon_set/blacks/16x16/br_down.png) no-repeat right #ddd;
    -webkit-appearance: none;
    background-position-x: 244px;
}

假设selectDrop是HTML标记中出现的类。所以,这么多代码足以改变默认的箭头图标:

.selectDrop{
      background: url(../images/icn-down-arrow-light.png) no-repeat right #ddd; /*To change default icon with provided image*/
      -webkit-appearance:none; /*For hiding default pointer of drop-down on Chrome*/
      -moz-appearance:none; /*For hiding default pointer of drop-down on Mozilla*/
      background-position-x: 90%; /*Adjust according to width of dropdown*/
    }

我设置了一个自定义箭头的选择,类似于Julio的答案,但它没有设置宽度,并使用svg作为背景图像。(arrow_drop_down from material-ui icons)

select {
  -webkit-appearance: none;
  -moz-appearance: none;
  background: transparent;
  background-image: url("data:image/svg+xml;utf8,<svg fill='black' height='24' viewBox='0 0 24 24' width='24' xmlns='http://www.w3.org/2000/svg'><path d='M7 10l5 5 5-5z'/><path d='M0 0h24v24H0z' fill='none'/></svg>");
  background-repeat: no-repeat;
  background-position-x: 100%;
  background-position-y: 5px;
  border: 1px solid #dfdfdf;
  border-radius: 2px;
  margin-right: 2rem;
  padding: 1rem;
  padding-right: 2rem;
}

如果你需要它也在IE中工作,更新svg箭头到base64并添加以下内容:

select::-ms-expand { display: none; }

background-image: url(data:image/svg+xml;base64,PHN2ZyBmaWxsPSdibGFjaycgaGVpZ2h0PScyNCcgdmlld0JveD0nMCAwIDI0IDI0JyB3aWR0aD0nMjQnIHhtbG5zPSdodHRwOi8vd3d3LnczLm9yZy8yMDAwL3N2Zyc+PHBhdGggZD0nTTcgMTBsNSA1IDUtNXonLz48cGF0aCBkPSdNMCAwaDI0djI0SDB6JyBmaWxsPSdub25lJy8+PC9zdmc+);

为了方便调整箭头的大小和间距,可以使用svg:

url("data:image/svg+xml,<svg width='24' height='24' xmlns='http://www.w3.org/2000/svg'><path d='m0,6l12,12l12,-12l-24,0z'/><path fill='none' d='m0,0l24,0l0,24l-24,0l0,-24z'/></svg>");

它在箭头两侧没有任何间距。

.select{
  -webkit-appearance: none;
  -moz-appearance: none;
  background-image: url("data:image/svg+xml;utf8,<svg fill='black' height='24' viewBox='0 0 24 24' width='24' xmlns='http://www.w3.org/2000/svg'><path d='M7 10l5 5 5-5z'/><path d='M0 0h24v24H0z' fill='none'/></svg>");
  background-repeat: no-repeat;
  background-position-x: 98%;
  background-position-y: 50%;
}
