 ### With icon only
 
-A button can even consist of an icon only.
-Do this only for icons that are universally recognized.
+A button may display an icon alone if its meaning is generally intuitive without a label:
+Examples: audio and video controls, close (cross), delete (trash bin), download (downward arrow), favourite (heart), menu (hamburger), save (disk), search (magnifying glass), settings (gear or cog) and toggle (chevron).
