Why do I see codes with
<!DOCTYPE html>
<html></html>?
How do they have 2 opening html tags? In quizzes it was stated that tags like these can't work, yet their codes still execute just fine on the code playground.
How?
when you are using HTML5 elements there must be these :
<DOCTYPE html>, this is not opening tag, it is DOCTYPE declaration for HTML5.
and then <html></html> are main tags.
edit : those codes are totally perfect.
