Your head element not is entirely in the correct location.
You have no bodyelement.
You are missing a character that closes off both of your meta elements.
You really should go back and review the practice projects because you seem to not understand basic HTML syntax. Also, it looks like you did the bare minimum to try and claim a certification.
Despite that it works apart from the failed elements, with ticks throughout, and I have tried to keep it simple indeed.
I can change points 1 to 3, point 4, I’m sure it says the Meta is self closing. I don’t see how those changes would affect the failed elements, so what would help with those?
