Sentence-case capitalization (where the first letter is capitalized) is AAD’s recommended style for most headings, subheadings, and captions, especially for the web. This style guide, for example, uses sentence-case capitalization.
A reminder: Omit the period at the end of your sentence-cased heading, even if the heading might be a full sentence. The exception to this rule are sentence headings that are exclamatory (where you end with "!") or that are in question form (where you end with "?").
