User blog comment:Rupert Giles/Layout Changes: Breakpoints and Typography/@comment-5558012-20150529032159

Another thing I'm liking as a direct result of this update is that I can optimize columns easier for both mobile and large screen users. Before breakpoints, images on some pages (for large screens) would drop down to where I wished to place some columns moving them thus more white space for the majority of users. After breakpoints, images on most pages don't move enough to affect columns thus they can be used leading to less white space (and scrolling) within the content. Coupled with some existing screen CSS, columns can be used much nicer across screen sizes.
