I am inputting the index.html, and keeps saying I am incorrect even though I have watched the video over five times.

This step is all about building navigation lists. The first step this code challenge asks you to do is to add the nav element. That can be simply done with <nav></nav>. Nav is an HTML 5 element that allows for more CSS customization that you will learn later. Then it asks you to put an unordered list inside without the list items. This will be done with <ul></ul> inside your nav tags.

The next step is to add the list items. List items are marked with <li> and are closed after the text with </li> you may have as many list items as you want, but this challenge is asking you to have 3.

The final step is to add the links. You start with an anchor tag <a> and add the attribute href="FILE PATH" then you have the words you would like to link followed by the closing </a> tag.

Your final code should look something like this:

<nav>
    <ul>
        <li><a href="index.html">Portfolio</a></li>
        <li><a href="about.html">About</a></li>  
        <li><a href="contact.html">Contact</a></li>
    </ul>
</nav>

Thank You!!
