Thank you.

HTML is markup language. It comes from an old form of “marking up” scientific documents so people could understand the sections and what was what.

With that, one of the first things you do when writing HTML code (language) is declare or inform which code (language) you’re writing in.

Tags have opening and closing tags <>and </>.

So step one for this will be “marking up” or declaring what language you will be coding in.
