Carbon is IBM’s design-system icon set for product interfaces and data
visualization. Icons are drawn on a 32×32 grid; many names have -alt or
filled counterparts. They use currentColor, so the preset’s auto mode
normally emits a CSS mask that follows the surrounding text color.
<span class="icon:carbon-sun" role="img" aria-label="Sun"></span>The exact collection prefix is carbon. Keep the icon name from the
searchable Carbon catalogue
when copying a token. Canonical kebab-case and camelCase forms are accepted;
arbitrary inserted hyphens are not. For example, the collection has an
add-alt icon, but changing another name’s word boundaries can turn a valid
class into an unmatched one.
Enable Icons in the CSS entry and scan the file containing the complete token. For the upstream collection, see the Carbon icon library.
