Link html pages to other html pages on chromebook

I wanted to make a website that would help people study better. It's still pretty basic since I don't actually know enough JavaScript to make it cool. I wanted to link one page to another through buttons, but I have no luck in doing so. I use a Chromebook and I had seen that the same link you'd use on a computer using windows isn't the same. Here is what I did, but nothing seems to work. It is saved in the folder, Websites and it's named About.html

HTML code

<ul>
  <li><a href="Websites/About.html">Home|</a></li>
  <li><a href="">About|</a></li>
  <li><a href="">Schools|</a></li>
  <li><a href="">Submit Notes|</a></li>
</ul>
