For school I must make a website and it must use those crappy old damn fml frames. I\'ve already complained about this to my teacher without any success :(<
You'll have to resort to XHTML or HTML 4.01 for this. Although iframe is still there in HTML5, its use is not recommended for embedding content meant for the user.
And be sure to tell your teacher that frames haven't been state-of-the-art since the late nineties. They have no place in any kind of education at all, except possibly for historical reasons.
