Describe your issue in detail here.

Hi team, i can’t complete this step:
Each .nav-link element should link to a corresponding element on the landing page (has an href with a value of another element’s id. e.g. #footer ).

Challenge: Product Landing Page - Build a Product Landing Page

Link to the challenge:

This seems to be referring to bookmarks.

Here is a link that may be helpful:
HTML Links - Create Bookmark (

Bookmarks will link to areas of your page.
For example you might want users to be able to jump to areas of your page using links in your nav list.
This means they wont have to scroll down to find something.
