css - 如何从 select 标签更改选项的背景颜色？

Question

我正在尝试更改 select 标签中选项的背景颜色。

我试过 select > option 但它不起作用。

我的代码如下:

select {
  width: 100%;
  height: 32px;
  background-image: url("images/2017_04_form_select.jpg");
  padding-right: 25px;
  /* Safari 3-4, iOS 1-3.2, Android 1.6- */
  -webkit-border-radius: 0;
  /* Firefox 1-3.6 */
  -moz-border-radius: 0;
  /* Opera 10.5, IE 9, Safari 5, Chrome, Firefox 4, iOS 4, Android 2.1+ */
  border-radius: 0;
  background-repeat: no-repeat;
  background-position: right center;
  -webkit-appearance: none;
  -moz-appearance: none;
  -ms-appearance: none;
  -o-appearance: none;
  appearance: none;
  border: 1px solid #bdb9bb;
  margin-bottom: 20px;
}

select:-moz-focusring {
  color: transparent;
  text-shadow: 0 0 0 #000;
}

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

select>option {
  background: #e8e4e6;
}

Answer 1

你只需要为select option设置一个background-color

select option {
  background-color: red;
}

<select>
  <option>Option 1</option>
  <option>Option 2</option>
  <option>Option 3</option>
</select>
