Can i use Iframe inside an Iframe?

Wouldn’t pulling in a nested iframe partially or fully obscure the parent iframe? I don’t understand why one might want to do this.

After reading a few opinions on the internet, including parts of W3C and MDN, I’m inclined to agree wtih @coothead, that nesting iframes is not possible.

One can give the illusion of nested iframes by putting the iframes in a parent container (such as a <div>) that has position:relative and assigning position:absolute to the to the iframe that you wish to appear inside and overlaying the other.

FWIW.
