Please review this theory lecture about the importance of using an HTML Boilerplate to start your projects.
Remember that most HTML elements, with the exception of void elements, require both a starting tag and an ending tag.
I highly recommend you format your code (You can do that in the fCC editor by right-clicking and selecting “Format Document”). It will make is so much easier for you to find missing end tags, etc. going forward.
Carefully review the user stories to make sure you have implemented them exactly as asked.
