What is the difference between Title Case and Capitalized Case?

It’s all about the "small" words. Capitalized Case forces every single word to start with an uppercase letter. Title Case is smarter - it follows English grammar rules by keeping articles (a, an, the) and short prepositions in lowercase, making your headings look professional.
