The seven cases explained
Sentence case capitalizes only the first letter of each sentence, which is the normal format for body text, emails and descriptions. lower case removes every capital letter, useful for tags, usernames and code. UPPER CASE capitalizes everything, the classic choice for warnings, acronyms and attention-grabbing headers. Capitalized Case starts every single word with a capital letter, handy for names and simple headings. Title Case is smarter: it capitalizes the important words but keeps short words such as a, of and the in lower case, the way book and article titles are written. Finally, aLtErNaTiNg cAsE and InVeRsE CaSe are playful formats: the first alternates letters one by one, and the second flips every capital to lower case and vice versa.
