I often use the HTML tag <small> in order make some text de-emphasized, to reduce it’s draw on the eye. In some cases this is literally to add small print, but usually just to add additional details that the user might need first time, but probably not again, so it doesn’t want to be noticed unless the user is looking for more information.
Today I needed the opposite. Large? No… <big>.
In Brave, and therefore probably all the Chromium browsers (eg. Chrome, Edge, Vivaldi, etc.), this gives you a font size that is 120% the size of the parent.
As they say, every day is a school day!
