更改下拉箭头的颜色和外观

Question

我想更改下拉列表箭头的默认外观,以便在浏览器中看起来相同.有没有办法使用CSS或其他方式覆盖下拉箭头的默认外观？

Answer 1

你可以用CSS实现这一点,但你并没有技术上改变箭头本身.

在这个例子中,我实际上隐藏了默认箭头并显示了我自己的箭头.

HTML:

.styleSelect select {
  background: transparent;
  width: 168px;
  padding: 5px;
  font-size: 16px;
  line-height: 1;
  border: 0;
  border-radius: 0;
  height: 34px;
  -webkit-appearance: none;
  -moz-appearance: none;
  appearance: none;
  color: #000;
}

.styleSelect {
  width: 140px;
  height: 34px;
  overflow: hidden;
  background: url("images/downArrow.png") no-repeat right #fff;
  border: 2px solid #000;
}

CSS:

<div class="styleSelect">
  <select class="units">
    <option value="Metres">Metres</option>
    <option value="Feet">Feet</option>
    <option value="Fathoms">Fathoms</option>
  </select>
</div>

Answer 2

不,跨浏览器形式的custimization是非常困难的,如果不是不可能的话,它适合所有浏览器.如果你真的关心那些小部件的外观,你应该使用javascript实现.

它可以通过以下方式完成:

select{

  }
