so for 5 and 6, first don’t worry, its all semantic errors. Your code has nothing wrong.
But what they actually want in story 5, is let your
nav-link class be the clickable
Example instead of:
<a href="#id">go to id</a>
<a class="nav-link" href="#id">go to id</a>
For story 6 it is similar, instead of
#video being on a wrapper, they want it on the
<iframe> element itself.
It may help in the future to read the error message a little further than the first line. For example, your story 5 error says: “Each .nav-link element should have an href attribute : expected false to equal true”.
This message is pretty clear on what the problem is, and fixing it becomes not that hard.
