You're not looking for an else, you're looking for <![if !IE]> <something or other> <!--[endif]>(note that this is not a comment).
您不是在寻找 else，而是在寻找<![if !IE]> <something or other> <!--[endif]>（请注意，这不是评论）。
<!--[if IE]>
You're using IE!
<![endif]-->
<![if !IE]>
You're using something else!
<![endif]>
You can find documentation on the conditional comments here.
您可以在此处找到有关条件注释的文档。

I use the following to load resources in IE9 or newer and all other browsers
我使用以下在 IE9 或更新版本和所有其他浏览器中加载资源
<!--[if gte IE 9]><!-->
//your style or script
<!--<![endif]-->
This is hard to believe. Look the opening and closing if statement sections are inside comments (so, its not visible to other browsers) but visible to IE.
这很难相信。查看 if 语句部分在注释中的开头和结尾（因此，它对其他浏览器不可见）但对 IE 可见。

The solution for your problem is (note the use of <!-- -->):
您的问题的解决方案是（注意使用<!-- -->）：
<!--[if lt IE 9]>
This is less then IE9
<![endif]-->
<!--[if gt IE 8]> <!-- -->
this is all browsers: IE9 or higher, firefox, chrome, etc.
<!-- <![endif]-->

conditional comments can be in scripts as well as in html-
条件注释可以在脚本中也可以在 html 中
/*@cc_on
@if(@_jscript_version> 5.5){
navigator.IEmod= document.documentMode? document.documentMode:
window.XMLHttpRequest? 7: 6;
}
@else{
alert('your '+navigator.appName+' is older than dirt.');
}
@end
@*/

You do not need to do an else. It is implied. So
您无需执行else. 它是隐含的。所以
// put your other stylesheets here
<!--[if lt IE 9]>
//put your stylesheet here for less than ie9
<![endif]-->

The accepted answer by @cwallenpoole breaks the markup, makes HTML invalid, and breaks Visual Studio's syntax highlight.
@cwallenpoole 接受的答案破坏了标记，使 HTML 无效，并破坏了 Visual Studio 的语法突出显示。
Here's how you keep it clean:
以下是保持清洁的方法：
<!--[if IE]>
You're using IE!
<![endif]-->
<!--[if !IE]><!-->
You're not using IE. See, even SO highlights this correctly.
<!--<![endif]-->

This worked for me, after hours of searching. I needed the head room for a pop-up banner, that IE didn't want to animate. it was supposed to hide itself after a few seconds. Using this, I was able to just move the entire page down just enough, but only in IE, which was exactly what i needed!
经过数小时的搜索，这对我有用。我需要一个弹出式横幅的头部空间，IE 不想设置动画。它应该在几秒钟后隐藏自己。使用它，我能够将整个页面向下移动到足够的程度，但仅限于 IE，这正是我所需要的！
Currently only for those who still use IE, I prefer FireFox or Chrome myself.
目前只针对那些还在使用 IE 的人，我自己更喜欢 FireFox 或 Chrome。
Thank you for these letters/symbols in this specific order!
