Title Case Used For Interface Text

Forbidden
"Add To Cart", "Save Post for Later?"
Instead
Sentence case: only the first word and proper nouns capitalised. "Add to cart", "Save post for later?"

What this rule looks like

Forbidden
Instead

Why this rule

Title case is harder to read — the eye expects lowercase, and each capital interrupts the scan. Its rules are also not standardised, so it is applied inconsistently even by people trying. Applies to headings, buttons, labels, menu items, table headers and dialog titles alike.
