How do I use CDN Link for my react app Markdown Previewer?

I can’t figure out how to use CDN link for my react app. I’m using VS code as my text editor not CodePen.

There is no HTML file.

Hi and welcome to the forum.
In case you used the create-react-app to create your react application, it creates the index.html file in the public folder. you can add the CDN link there.

you can find more about the create-react-app structure here: Folder Structure | Create React App

thanks! It worked for me
