Bootstrap is compatible with media queries in ie8 and bootstrapie8

When I recently used bootstrap for my website, I found that the media query in ie8 has always been invalid:

Later, we solved the problem and made the following record:

1. It must run under the server

2. the hack condition syntax is as follows:

<! -- [If lte ie 9]> <script src = "js/html5shiv. min. js "> </script> <script src =" js/respond. min. js "> </script> <! [Endif] -->

In this case, ie9 also loads the above two documents and changes them to [if lte ie 8] or [if lt IE 8]. I don't know why, if anyone knows, please leave a message. Thank you!

3. If there is a problem with the js plug-in the framework, it is common that the collapsed navigation icon does not display the drop-down menu. We recommend that you use jQuery1.x.
