Flagpack supplies country flags on a 32×24 grid. Names use lowercase
country codes; the preset prefix is flagpack. The SVGs are multicolor, so
Icons’ default auto mode emits a CSS background image rather than a
single-color mask. A surrounding color property does not recolor a flag.
<span class="icon:flagpack-nl" role="img" aria-label="Netherlands"></span>Use a visible country name when possible. If a flag is the only content that
conveys meaning, give it an accessible name; if text already identifies the
country, mark the icon aria-hidden="true". Flags alone can also be
ambiguous for language selection, where the language name is clearer.
