Product landing req help

Tell us what’s happening:
Hi there, was wondering if anyone familiar with the product landing requirements could glance over my code and see if you can identify what requirement I am not fulfilling, I am having trouble figuring that out. Also the assignment sheet I am looking at for the product landing project has 15 requirements but the test I embedded in my page has 16, so I was wondering what the extra req was. I have only been at html and css for a week so any pointers on the code would be welcome and helpful.

Your code so far
