Can I use Full screen iframe in my webpage of my other website?

I have hosted a website on GitHub but I cant share that url as it's too long.

So, I have created a webpage from blogger with custom url and set my GitHub website into the full screened

If have to display Google ads in that website, will it be legal, as Google may think that the GitHub website used in iframe is not mine? Will Google see the code of my website before approving it?
