NavBar issues

Just copy one of the good navigation <li></li> from the code and replace the bad one with the good one then change the link to 'Home'

Just looking at the code you have duplicate <a> tags and classes - you could amend that quite easily but copying and pasting a good line of coding is going to be easier for you.

Fix your coding errors.

Your opening ul is not closed, you have 2 closing a tags for the first li.

Then run the rest of your page through the validator.
