For less bandwith usage web servers serves compressed datas over HTTP. Supported compressions are told to the server by the browser in Accept-Encoding request header. In response, the server uses Content-Encoding representation header to let the browser know which compression it is using. As of Chromium 94.0.4606.54 Arch Linux, it sends gzip, deflate, br. 'br' stands for Brotli, successor of gzip.
In Chrome/Chromium, press CTRL+i to open developer tools. Click 'Network' and visit a webpage. From the list of connected domains, you can choose a domain and see what compression it used under section 'Response headers' in 'content-encoding' field. As of https://superuser.com, the content-encoding is gzip, i.e, the HTML, JS and CSS are served gzip-compressed.
