I would suggest you add .offset4 as a class to that element as that would normally offset the element so it appears to be on the far right, but that doesn’t work because your version of Bootstrap seems to be weird and isn’t using very good media queries. Have you edited it?
I’m not really sure what to suggest. Bootstrap’s class names don’t seem to work. You’ve got 2 elements that both span 4 columns each, so it should be possible for you to add .offset4 to the second one and have it appear to be on the far right (there’s a max number of 12 columns), but that doesn’t seem to be working.
