CSSType - Strict CSS Type Definitions

CSSType provides comprehensive TypeScript and Flow type definitions for CSS properties and values, meticulously generated from MDN data. It is currently at version 3.2.3 and maintains an active release cadence, frequently updating its definitions to reflect the latest CSS specifications and browser compatibility data. Key differentiators include its strict adherence to MDN, support for various property naming conventions (camelCase for JavaScript, kebab-case for CSS-in-JS libraries), and inclusion of fallback array types for properties that accept multiple values. It covers standard, vendor-prefixed, obsolete, and SVG-specific properties, along with at-rule and pseudo-class/element types, offering robust type checking and autocompletion for web development projects.
