Technical Documentation Page - Build a Technical Documentation Page

Failed:All of your .nav-link elements should be in the #navbar.*
Failed: Each .nav-link should have an href attribute that links to its corresponding .main-section (e.g. If you click on a .nav-link element that contains the text “Hello world”, the page navigates to a section element with that id).

Failed: Your Technical Documentation project should use at least one media query.

Challenge: Technical Documentation Page - Build a Technical Documentation Page

Link to the challenge:

you have to attempt to follow the html rules you learned in the curriculum.

For eg. the link element belongs in a head element
The navbar needs internal links inside (you use “#Introduction” for the href for eg to link to an internal id on the page)

Anchor tags need proper links inside their href, not text.

You need to add missing elements to your navbar to link to each section you have created.
