title: How to separate my demo website from my personal Github page
body: <p>So I have a .github.io personal github website and currently inside the website, I have one page that serves as a demo page for my web application project(its a simple single page application).</p>
  
  <p>Now I want to separate that page and create a new repository for it so that making changes to it does not affect my personal website. However, I still want to navigate to that page with .github.io/.</p>
  
  <p>Currently, I have a repository for my demo page and an index.html, but doing the above gives me 404 page not found.</p>
  
  <p>Is there a way this can be done?</p>
