Frequently asked questions

What is the difference between title case and sentence case?
Title case capitalises the significant words in a heading, while sentence case capitalises only the first word and any proper nouns, exactly as you would write an ordinary sentence.
Which small words stay lowercase in title case?
Short articles, conjunctions and prepositions such as a, an, the, and, or, of and in stay lowercase unless they open or close the title. Style guides disagree on the exact list.
When would I use camelCase or snake_case?
They are programming conventions. JavaScript and Java favour camelCase for variables, Python and SQL favour snake_case, and kebab-case is standard in URLs, CSS class names and file names.
Does converting case damage accented characters?
No. The conversions use the browser locale-aware case rules, so accented letters and non-Latin scripts are handled correctly rather than being stripped.
