The 12 styles, and when to use each
- UPPERCASE – short labels, warnings, form fields that ask for block capitals.
- lowercase – tidying data before comparing it, hashtags, email lists.
- Title Case – headlines, book and film titles, blog post titles.
- Sentence case – body text, and headings on sites that prefer a calmer look.
- Capitalize Each Word – names in a list, product labels, menu items.
- aLtErNaTiNg – mocking memes and playful captions. It alternates only letters, so spaces and punctuation don't upset the pattern.
- iNVERSE – swaps every letter's case, which instantly repairs text typed with Caps Lock left on.
- camelCase and PascalCase – variable, function and class names in JavaScript, Java and C#.
- snake_case – Python variables, database columns and file names.
- kebab-case – CSS class names and URL paths.
- CONSTANT_CASE – constants and environment variable names.
