A taxonomy term classifies content by topic. Shown on a card as a tag, it tells at a glance what the content is about and can lead to the term page, which gathers all the content sharing that topic.
Combining cards and terms lets visitors browse a site by subject rather than by section, while keeping a consistent presentation from one list to another: the same card works in a grid, a list or an “other pages” block, only the tags change.
