推荐答案
难以自定义<select>& <option>标签
<select>和<option>标记很难自定义，任何对一个浏览器都适用的标记对其他标记都不适用.
It's Difficult to Customize <select> & <option> Tags
<select> and <option> tags are difficult to customize and anything that holds true for one browser is never true for the rest of them.
- 忘记自定义
<select>，使用<details>和<summary>创建伪
<select> ✱
- 忘记自定义
<option>，使用<input type='radio'>和<label>创建伪
<option> ✱
✱伪<select>和伪<option>标签的外观和行为将与标准<select>和<option>标签的相似.更重要的是，它可以存储和处理value，并且可以将其注册到change事件.
✱The pseudo-<select> and pseudo-<option> tags will be close in appearance and behavior to that of the standard <select> and <option> tags. More importantly, it can store and process a value, and it can be registered to the change event.
