Reduce top padding on .columns-inner?

Issue Summary

Sky has too much whitespace before the breadcrumbs for my use-case. If I set this in page.css:

Then the breadcrumbs (or the first div inside of columns-inner) gets displayed at the center of the page, instead of left. This happens only on full browser widths; on a smaller browser window or a mobile device, it looks fine.

I'm sure there is some other positioning/layout selector that I need to adjust when adjusting padding-top on .columns-inner. What might that be?

Thanks!
