Off-centre split

Two columns of clearly unequal width. Says which side matters most, and keeps the other at hand.

Good for: Buy boxes, checkouts, text with notes or a summary beside it.

Weak for: Two things of equal weight, which look as if one was forgotten.

The narrow side drops below (or above) the wide one on phones; decide which comes first.
