## CSS Features (last 5 years)

Feature availability data generated from MDN Browser Compatibility Data (BCD) at build time. Each entry lists, per browser, whether the feature works without a vendor prefix, requires a prefix or alternative name, or is not supported.

"Full browser support" means the feature is usable (with or without a prefix) in every browser listed below — safe to suggest without asking which browser the user targets. "Partial browser support" lists exactly which of those browsers support it — only suggest this feature when the user's target is limited to one of the listed browsers. [DEPRECATED] / [EXPERIMENTAL] tags reflect BCD status flags and mean the feature should generally not be recommended for production use.
