Editorial Standards

Editorial standards

CSS Mastery exists to help developers understand CSS behavior well enough to make durable production decisions. Each page is reviewed against usefulness, originality, technical accuracy, accessibility, and policy compliance.

Originality

Guides must add first-hand implementation judgment, not just restate documentation. When a page references MDN, web.dev, W3C material, or browser documentation, it must explain the practical consequence for a developer's work.

Code quality

Examples should be minimal, runnable, and scoped to the behavior being explained. Code snippets should avoid framework-specific assumptions unless the page is explicitly about framework integration.

Accessibility and performance

Layout and styling advice should consider keyboard access, reduced motion, contrast, reading measure, reflow, and layout stability when those concerns affect the pattern.

Advertising separation

Advertising must be clearly labeled and visually distinct from navigation, downloads, code examples, and recommended resources. The site must never ask readers to interact with ads.
