If you work in an environment that has multiple versions of Internet Explorer and trying to support SharePoint 2013, you will need to add a simple HTML tag to your master page/custom master page in order to be truly backwards compatible especially if you have IE 8 or IE 9 in your environment.
Place this tag in your <head></head> section in your start page.
<meta http-equiv=”x-ua-compatible” content=”ie=edge”>
This will help with forward and backwards compatibility.
Please TEST in your test/development environment(s) first before applying to your production site.
There are times where I need to view a website but the website is not ready for Internet Explorer 9. But how can I change Internet Explorer 9 so that I can view it in compatibility mode?
Well in Internet Explorer 9, the location is buried. So I am writing this blog post so I can reference it. I am sure there are other fellow technologists out there that need the same information. I hope this helps people out.
[box]1. Right Click on the sprocket on the top-right hand side.
2. Checkmark Command bar. (You should now see the command bar.)
3. Choose Tools ==> Then Compatibility View Settings.
4. Then Kapow! You are now view it in other IE settings. [/box]
