This MR is a follow-up to these two MRs:
Using the added styles that was suggested here: !54934 (diffs, comment 520072557).
Note: there is a minimal change in margin on the right side of the purchase flow in Medium screens and above. This is due to there being a style, px-lg-7, that did not actually exist before.
