How to get a preview of a page on GitHub?

[a-new-insight]

I made a site. But, Lightspeed Filter Agent (which i really hate) blocks it for "Domain Sharing", so I want a preview of a page without going to the hosted site. Anyone know how?

Since your network blocks the hosted site, you can preview your HTML files locally before pushing. Just open the HTML file directly in your browser from your computer (File > Open File), or use VS Code with the Live Server extension to run it on localhost. That way you can see the preview without needing to access the GitHub Pages URL.

I can't download stuff including VS Code, and I can't preview locally because "file links are blocked".
