Country and region flags are provided as square 24 × 24 SVG icons. Codes follow
ISO 3166-1 alpha-2
with a handful of additional codes for subdivisions (for example gb-eng, es-ct)
and supranational entities (eu, un, cefta).
The flag image is decorative; click the code (for example md) to copy ready-to-paste markup using identifier flag-md. Flags are served from the
open-source flag-icons
library via jsDelivr.
