I am validating my website in W3schools and i get 1 error saying 'Missing xmlns attribute for element html. The value should be: http://www.w3.org/1999/xhtml
But when I insert this I get more errors of 24 errors.what is going on?what is this xmlns attribute?
To change it I take my html out and replace it with: html xmlns="http://www.w3.org/1999/xhtml">
what am i doing wrong?
Help is appreciated.
