I have to make a page that thinks of a random number and then with an input enter that number, if it is not the random number that tells me if it is smaller or bigger.
Well, what I find a problem is that when I input an input does not tell me if it is greater or less, eye! It has to be without pressing a submit or anything that tells me if it is bigger or not
