我在选项中遇到样式问题。我需要一些选项以粗体样式显示，但Internet Explorer不想渲染它。

推荐答案

的< option> 元素。这是因为IE使用Windows窗体控件来渲染选择框，它不支持此功能。

IE doesn't allow styling of <option> elements independently. This is because IE uses a Windows form control to render the select box, which doesn't support this feature.

（另一方面，这与IE的选择框在将其放在其他对象后面时可能会出现分层问题;表单控件由Windows操作系统呈现，而不是由浏览器呈现，因此浏览器对该页面上的大多数其他元素的控制较少）

(as an aside, this is the same reason that IE's select boxes can have issues with layering when you put them behind other objects; the form control is being rendered by the Windows OS, not by the browser, so the browser has less control over it than most other elements on the page)

其他现代浏览器允许你这样做，因为他们渲染自己的选择框而不是推迟到操作系统。

Other modern browsers do allow you to do it, as they render their own select boxes rather than deferring to the OS.
