Well, If You take a look at my project, You will see that I created alternative solution, which is a div element that is invisible in the same place as iframe, and it is possible to change visibility of them both and choose what is needed at the moment(I thought about using div but it looked for me too easy). But can I change the language od such div? Or can I open another webpage in it? It is hard for me write right now how mamy things are possible with iframes. I like to think about myself as a person who "pushes the limits". Using frames I hope will help me better understand how it all works. And also important for me is to keep things in logical structures, it makes possible to operate on bigger, more complex objects. Changing textarea to editable div(so it would look realy cool) crossed my mind, but now have a lot work to do.
