So I embedded a facebook page on my website, Doesn't the embedded facebook page show when I am not connected to the internet?

I embedded a page from facebook to my website, when I am trying to load my website offline since I'm working on it for a project for school, the facebook page does not show. But when I try to load my website online it shows. Is this normal? can I embed a facebook page and show it offline since I need it for school without internet access.
