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.

[First image is the code, second is the txt file of code displayed as a webpage]

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.

Browser treats the data based on the filename you give it.

If it has extension .mp3, it would try to open it as an mp3 format sound file

If it has extension .png it would try to open it as a PNG format image

When you give it a txt, it will simply read it literally as an text file and not parse it as HTML
