Hi all! I have a problem with the following tasks, at the end of the exercise the manager shows this message:
This is the error message:
"Oops, try again. Did you remember to give your #header a position of fixed?"
I'm quite sure that the code is ok, can you please help me?
Many many thanks

Instead of this line:

write this line:

<link type="text/css" rel="stylesheet" href="stylesheet.css"/>
