how to link my style.css
I think we’re having the same issue, but you haven’t described it in enough detail. I have a simple HTML page and main.js and style.css files in the same folder as index.html. In the HTML file, I have references to these files. Locally on my PC, everything works, but after launching it in idx, in the preview, I see that index.html doesn’t see the linked CSS and JS files.
