cssdb
ReferenceLists CSS features by how far along they are in becoming standards, with the browsers that support each one.
cssdb is a list of CSS features and where each one stands on the path to becoming an implemented standard, ranked by stages. It is maintained by CSSTools, the team behind postcss-preset-env.
Each entry has a short description, a code example, its Baseline status, browser versions from MDN data, and links to the spec and MDN. Entries also link to PostCSS plugins or JS libraries that polyfill the feature, many of them bundled in postcss-preset-env.
The data is published as the cssdb npm package and the repo is under MIT-0.
