A very simple example to determine if the version of Internet explorer is too low
The structure of the example is as follows. In fact, one page plus the introduction of jquery is enough, and a standard structure is created by the way (notice that the prompt effect of IE6 and IE7 is not seen until the version is lower).
< img SRC = "border = 0 / / files.jb51.net/file_images/article/201311/201311221642081.gif? 20131022164231 ">

} 
}
