Use preferred aspect ratios with automatic sizing and inspect competing constraints. Distinguish a replaced image’s natural ratio from its CSS box and object-fit behavior.

Choose whether a 3D-transformed back face is painted. Compare front and reverse states and account for accessible interaction when building a multi-face interface.
CSS / Reference / text-align: Text, Inline Content, and Block Alignment
Align text by physical or logical sides and distinguish it from centering a block. Inspect justification, final lines, and direction-sensitive layouts.
