Why i am getting the error like nav should should always be at the top of viewport?

Please help.

you need to add position: fixed to make it stay there when you scroll down.

I noticed it really needs some styling there. It will look very nice after.

Thanks, will update and post again.

It has an ID of header, not a class of header.

Hint (blurred, click to reveal):

A hash means an ID, a . means a class.

Tip: in codepen, to get some lorem ipsum text type lorem and then press Tab.

Thanks for the hint.

You also need to add the name attribute to the input of type email.
