Word to know
Favicon
The tiny icon on a browser tab and in bookmarks.
Also called: tab icon, the little icon, browser icon, bookmark picture
The small square image beside a page name on a browser tab, and next to the site when someone saves it as a bookmark.
Using it in a prompt
Add a favicon using the logo mark on a cream background, and check it is still legible at a very small size.
Small, easy to forget, and noticed when missing, because a site without one shows a blank page symbol in a row of branded tabs.
Detail disappears at that size, so a single letter or a simple mark reads far better than a full logo squeezed down.
