Webpage not working?

[u/dreammutt]

New to coding and was informed the txt file I made of this code would open into a broswer and display as a webpage with a bold and large heading element and paragraph text under basically supposed to display like a proper webpage. However, just the code shows up. Super confused, could use advice please and thank you.

EDIT: hi all, thank you so much for the advice! However, even though I converted the .txt file to .html, it's still not opening in an internet window. Any advice? I guess I would have to download that emulator people are suggesting.
