Meta tag X-UA-Compatible

x-ua-compatible is a new setting for ie8, which is not recognized by browsers other than ie8. This difference is like using the standard mode of Windows Internet explorer 7 regardless of whether the page contains <!doctype> commands. The content=ie=emulateie7 mode follows the <!doctype> instruction. For most websites, it is the preferred compatibility mode.

For most websites, it is the preferred compatibility mode.

Most sites were established before the official version of ie8 was released. We did not take into account the compatibility of ie8 before. Therefore, in order to avoid errors in the pages produced below ie8, it is recommended to directly render ie8 using ie7. That is, add the following code directly to the meta tag of the page's header:

<meta http-equiv=x-ua-compatible content=ie=7' />

In this way, we can make the page perform normally in ie8!
