Use initial caps on all words except articles and conjunctions of four or fewer letters. Example: Going to Sea with the Young Man
Titles that would otherwise take italics (books; magazines; newspapers; seagoing vessels, aircraft, and spacecraft) should receive single quotes in titles
Be mindful of headline length. You should strive to keep headlines to a depth of one line when published. Check your titles after they appear on the site. Under no circumstances should a title be more than two lines deep; that just looks crazy.
