The Page With No Code (via) A fun demo by Dan Q, who created a web page with no HTML at all—but in Firefox it still renders content, thanks to a data URI base64 encoded stylesheet served in a link: header that uses html::before, html::after, body::before and body::after with content: properties to serve the content. It even has a background image, encoded as a base64 SVG nested inside another data URI. # 21st January 2023, 6:59 pm
