It shows me error ‘Your DOCTYPE tag doesn’t look quite right. Did you type it like this: <!DOCTYPE html> ?’
The browser executes this code with no problem, but your editor is not
I do not understand what you are talking about.
In the instructions said:
" In between the second and last line (between the html and the /html), feel free to write whatever message you like."
There is no word about h1 or else.
Why the editor in the lesson does not except my code?
