Product landing page problem : not passing the test

Not sure why I can’t pass this test (at the moment it’s 15/16). I am stuck.
Maybe someone could check and give me a hint what is the problem?

Thank you!

Link to the challenge:

if you click on 15/16 you can see the not passing test, even if I have no idea what’s the issue

  1. The navbar should always be at the top of the viewport.
    #header or one of its children should be at the top of the viewport even after scrolling : expected 500 to be close to 0 +/- 15

Add the fixed-top class to the header element.

You can keep it on the nav. If you do remove it from the nav the width of the header will look like it’s the size of the container. You can give the header element the same gray color to fix that.

Thank you! It’s ok now.
