In today's HTML tutorial, I'll show you how to format text with subscripts and superscripts. Using the "sub" and "sup" elements, we'll create formulas like "c" square with index 1 equals "a" with index 1, plus "b" index 1. It's simple—wrap the text in "sub" for subscripts and "sup" for superscripts. Watch, learn, and don't forget to comment and subscribe for more tutorials!
