If IE8 is displaying all Bootstrap columns full-width, here’s the fix
I see a lot of reports online that Bootstrap 3 is not correctly displaying on IE 8, for example two side-by-side columns get displayed full-width and stacked (instead of side-by-side).
If you’ve already added the required IE8 patch shown below, be sure you are adding that after the bootstrap.css file is loaded. (If you load it before boostrap.css it will not work.)
