I Have seen several posts regarding this feature to preview HTML file on GitHub. Some suggest prepending https://htmlpreview.github.io/ before the real URL and some suggestions to create GitHub pages that I don't want to do now because then I have to re-create most of the thing on .yml
But my confusion is why this link showing HTML preview but not mine when I prepend the same string on my repo's HTML page. Please let me know If any other way I can see the HTML preview on github
