Frequently asked questions
Why is my title case wrong for small words?
Classic title casing keeps articles and short prepositions lowercase (a, of, in); toggle "smart small words" to control this.
What is the difference between Title Case and Sentence case?
Title Case capitalises the significant words ("The Art of War"), while Sentence case capitalises only the first word and proper nouns ("The art of war") - publishers differ on which they require.
When would I use snake_case or kebab-case?
snake_case is the convention in Python variables and database columns; kebab-case is the standard for URL slugs, CSS classes and package names.
