how to see what class attributes we have?
...because i cannot imagine from which place we received a data in our key (main) function of this lesson.

The ".className" property of an element will contain all the class names assigned to that element. Is that what you were asking in the first question?
But I don't quite understand the 2nd question, could you rephrase and/or elaborate a bit?
