okay so i created this season greetings website and used github to host it live,but it displays a github page i don’t seem to understand

[first step
output
where where the problem is ](https://stackoverflow.com)
so when I pass through the first the stage, get my output and send it to someone through the WhatsApp link, it always show the GitHub part
I just want it to display the output to whomever clicks the link sent via WhatsApp, or does this have to do with the fact GitHub can't handle it, maybe I need to host it? like domain stuff and the rest
I was expecting it to showcase when I send it via WhatsApp, to display what came out as the output
