'How do I link a react build from my main html

I am new to web development and I created a react app and built it. I renamed the index.html to react.html. In my main index.html I has this link.

a  href="react.html">react</a>

When I click it it just gets a blank page. Is there some better way that works? I also put the index.html into the build file.

html reactjs

Is there any id, like id="root" or id="app" or something where the react app will render something?
