CSS Grid IE bug workaround?

Hi guys,

I’m hoping somebody has come across the same issue and can help me. I’ve used a lot of CSS Grid to create a layout for a project I’m working on but I’m having issues with IE. I’ve listed read-only link below to the project and some screenshots showing how IE is rendering.

Does anybody have a workaround for fixing CSS Grid in IE without me having to rebuild in something like Flexbox?

Edit: the above screenshots are from IE11 Windows 10.
