A grid like this is possible?

[Energypac]

I am trying to build a custom grid and it works on everything but IE. here's the code below, any ideas. I need a 100% 240px overtop of (25/75) widget -primary content with the 240px to be able to run top to bottom. See tmp dump for an example. https://tmpdmp.com/d2490f00fae4a360/d5b39b0d14cebc80 While we're asking, I could use another one that is basically the same as the one above except 100% primary content on second line with the 240px to be able to run top to bottom
Thanks
