You are talking about your HTML. It should work with all major browsers, not just IE. Chasing all IE defects is pointless. Better make your HTML design simpler and less sensitive to all those IE freaky peculiarities.

He cannot. Browser doesn't provide any details whether it was by request changed to IE 8 or whether it is actually IE 8.

The only solution is to let user know that he should use IE 11 or above (IE Edge) to use the website (server-side code would help to detect the user-agent), otherwise he cannot. I don't think a good web developer would do so. Most of the users (that actually pay for stuff) use IE 9 or IE 10. IE 8 is not used too much now. Please see Solution 1.

Browser won't let you know, and JavaScript is abstracted from your browser's code. JavaScript is able to work only in a sandbox for your website. Meta tag and CSS or other similar techniques (are you talking about <![endif]-->?). But they would not work.

These only let you know of the current document mode, not the software installed. So you are left with no other option. Also they are not supported officially. Just a hack. Please see Solution 1.

In addition to Solution 1: please read my advice on browser compatibility:
webpages layout change when running in different browsers.[^],
How Do I Convert Desktop Site Into Mobile Site[^].

Main idea here is: you cannot chase all those browser peculiarities, especially with IE. The really best way is to develop Web design and layouts to make it not so sensitive to those peculiarities, which is achieved through reasonable simplicity. Believe me: nobody want's to see "cool" sophisticated tricks; people want good readability, useful interesting content and clear navigation.

You cannot do so. Because has himself changed the state of browser. Let me tell you, a user would never do that. Only if he is a developer or a hacker; cracker if in negative sense. Then he would try to play around with developer tools.

My younger brother doesn't even know that he can change IE document mode from Edge (latest version, not the new browser Edge) to IE 8 or 7 or 6. My father don't even know there is such a feature; developer tools. My grandfather doesn't even know if there is an IE. So, it depends on the users.

If he wants to open a document in IE 8 mode, he can. You cannot change that. Because browser doesn't tell website whether user is changing the document mode, or whether it is the actual browser with 8th version (of IE). Also, what makes you so sure that user, if still in IE 11, cannot remove jQuery itself? Or what if he doesn't even allow your website to send a request to download the library. There are many things.

Also, read the first comment to your question: Make designs to your website in order to provide a same functionality. Or simply, tell the user to use IE 11; worst UX technique. To handle browsers that do not support a feature, you should try using Modernizr[^].
