<!-- Test Description: The first few bytes in this document are \xef\xbb\xbf\xef\xbb\xbf, which is also known as a byte-order-mark (BOM). These are not renderable bytes and many text viewers will not display them. However, they are also not whitespace. An HTML5 compliant parser will open the <body> section immediately upon encountering non-whitespace text outside of the body section. This causes tags which appear to be in the document head to actually be placed in the document body. This creates very confusing errors which are hard to debug for most developers. --> <!doctype html> <html ⚡> <head> <meta charset="utf-8"> <link rel="canonical" href="./regular-html-version.html"> <meta name="viewport" content="width=device-width,minimum-scale=1"> <style amp-boilerplate>body{-webkit-animation:-amp-start 8s steps(1,end) 0s 1 normal both;-moz-animation:-amp-start 8s steps(1,end) 0s 1 normal both;-ms-animation:-amp-start 8s steps(1,end) 0s 1 normal both;animation:-amp-start 8s steps(1,end) 0s 1 normal both}@-webkit-keyframes -amp-start{from{visibility:hidden}to{visibility:visible}}@-moz-keyframes -amp-start{from{visibility:hidden}to{visibility:visible}}@-ms-keyframes -amp-start{from{visibility:hidden}to{visibility:visible}}@-o-keyframes -amp-start{from{visibility:hidden}to{visibility:visible}}@keyframes -amp-start{from{visibility:hidden}to{visibility:visible}}</style><noscript><style amp-boilerplate>body{-webkit-animation:none;-moz-animation:none;-ms-animation:none;animation:none}</style></noscript> <script async src="https://cdn.ampproject.org/v0.js"></script> </head> <body data-foo> Hello, world. </body> </html>
