Code Guide is a well-known HTML and CSS style guide by Mark Otto (@mdo), published as a static site built with Jekyll. It codifies standards for writing consistent, flexible, and sustainable markup and stylesheets.
Use cases
- establish html and css coding standards for a team
- learn best practices for writing maintainable css
- define style guide for frontend code reviews
- find recommended css declaration order and class naming conventions
- onboard new developers to consistent html syntax rules
When to choose
- you need a battle-tested, widely referenced HTML/CSS style guide to adopt or adapt
- you want a concise reference for syntax, attribute ordering, and CSS organization conventions
- you're setting up frontend code review standards
When to avoid
- you need automated linting or enforcement rather than written guidelines
- you need style guides for JavaScript or other languages
- you want a configurable tool rather than a static document
