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?

Yes, sorry, but where is this class names, assigned to that element? When i wrote " li.className " in console.log, i dont see nothing. second is about this function: if (li.className === 'responded') { li.style.display = ' '; } else { li.style.display = 'none'; } Thanks.

I can't be sure without seeing the whole code, but perhaps the element doesn't have any class name(s) assigned to it, and so the property is empty.
