So, I am a little late to make this post because I did not know I needed to😅. But, late is better than nothing! So, welcome to my version of how to comment with HTML aka All the Cool Stuff in YouTube comments that you never knew how to do! Oh, by the way, commenting with HTML refers to bolding, underlining, and italicizing text!
To make a word bold, simply put <b>(insert word here)</b> around it!
To italicize a word, simply put <i>(insert word here)</i> around it!
To underline a word, simply put <u>(insert word here)</u> around it!
I hope you found this helpful!
