Testing older IE browsers using IE 11 emulator

You may notice the IE8 styles are not being loaded in when testing through IE11’s browser emulation feature. This is due to changes in how IE11 reads IE conditionals and the introduction of the User Agent switcher. IE11 no longer supports conditionals, but there are some ways to make the emulation work. To set up your testing environment to be more accurate you will need to do two things:

  1. You will need to add a meta tag to the head of your pages:
    <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE9">
    Change the “IE9” part to match whichever version of IE you are testing for.
  2. Change the “User agent string” in IE11’s dev tools to match the version you are testing.

This should allow you to see the correct version of the Gridset CSS, whether you are using the Embedded CSS Link or the downloaded files.

Note: The best way to test IE would be to use Virtual Machines. You can find all the resources you need to set up Virtual Machines with IE here: http://www.modern.ie/en-us/virtualization-tools#downloads
