How saving works: this site has no server. Your edits live in this browser only until you click Save & Download HTML — that gives you a fresh BetaTANK Website.html with your changes baked in. Upload that file to your host (Netlify Drop, GitHub Pages, your cPanel, etc.) and the new content goes live for everyone. Quick free hosting tip: drag the downloaded file onto app.netlify.com/drop for an instant public URL.
