推荐答案
这是一个工作示例.- 单个选择选项无法设置样式.
Here is a working example. - A single select option cannot be styled.
我们在这里所做的是使用在点击时触发的 size
将选择更改为多选.转换为多选后,您可以设置选项悬停样式.
What we are doing here is changing the select to multiple selects using size
which is triggered onclick. Once converted to a multiple select you can then style the option hover.
.blue:hover {background: blue;}
.green:hover {background: green;}
.red:hover {background: red;}
<select onfocus='this.size=3;' onblur='this.size=0;'
onchange='this.size=1; this.blur();'>
<option class="blue" >blue background</option>
<option class="green" >green background</option>
<option class="red" >red background</option>
</select>
