Terms and definitions of capitalization case styles.
Title Case
Title case capitalization would have the first letter of every word capitalized, except for the articles (a, an, the, etc) within the phrase.

The Lion, the Witch, and the Wardrobe
Title case capitalization is best for professional or very formal use. Is your ideal client a group of professionals who work somewhere within a very traditional corporate atmosphere, like a law firm or accounting firm? Then title case is your best bet.
Sentence Case
Sentence case capitalization means only the first letter of the first word is capitalized, just like in a sentence.

5 capitalization styles you need to know
Sentence case capitalization is best for a more casual use, but can still be semi-professional.
A note on this: if your phrase begins with a number, like “4 capitalization styles you need to know,” then the number is the first word of the sentence. Therefore, you wouldn’t capitalize the next word.
Upper Case Capitalization (All Caps)
Only use for headings or titles, not an entire design. Beware of using acronyms and upper case capitalization, as it can cause confusion (ex: USA-BASED FIRMS)
Upper case capitalization means every letter of every word is capitalized.
