Two-letter words are only lowercase when they are prepositions or conjunctions, like "of," "in," or "or." "No" is neither.

"No" in Sentence Case
APA reference lists, many news sites, and most UI text use sentence case instead of title case. There, only the first word and proper nouns get capitals, so "no" is lowercase unless it starts the title: "No more excuses." Pick one of the two styles for a whole set of headings rather than mixing them.
