WHAT IS THE COLOR CODE OF MOZILLA IN THE PAGE INFO WINDOW - view-source. When looking at page coding in basic HTML 5 (4 transitional), what do the different colors mean? Especially RED! Blue too. Now it is obvious that this is "deprecated" HTML code, however, SINCE THE SITE IS DISPLAYING WHAT IS PROGRAMMED - is it that important? No CSS or other programming (frames, padding, etc. etc.) / Using old windows XP OS, which they will have to pry from cold dead fingers, but that is unrelated to this question
