Does chrome have some kind of strict code review mode?

Question

Google Chrome

Where everything is more strictly checked, I just sometimes screw up with closing tags, but chrome displays it, but firefox does not and I only notice it when I check through firefox, I work mostly in chrome. Is it possible to enable a more strict syntax checking mode in it or whatever?

Answer 1

How can you mess with closing tags?
Do you write them by hand? Moreover, the backlight always swears
