The interface would be slightly different but there&#x27;s no reason why an interactive map viewer couldn&#x27;t be done in pure HTML and CSS without JS, and then JS added for more enhancements like AJAX loading.<p>In fact... it&#x27;s been done <i>eight</i> years ago:<p><a href="http:&#x2F;&#x2F;www.appelsiini.net&#x2F;2008&#x2F;google-maps-without-javascript" rel="nofollow">http:&#x2F;&#x2F;www.appelsiini.net&#x2F;2008&#x2F;google-maps-without-javascrip...</a><p><a href="http:&#x2F;&#x2F;www.appelsiini.net&#x2F;2008&#x2F;google-maps-without-javascript-part-2" rel="nofollow">http:&#x2F;&#x2F;www.appelsiini.net&#x2F;2008&#x2F;google-maps-without-javascrip...</a><p>Look at where the map images are coming from, copy the link, and play around with the URL parameters. Yes, this still works.<p>I also distinctly remember playing some HTML adventure games with similar pan&#x2F;zoom&#x2F;click interfaces before the millenium, and they didn&#x27;t require JS either (nor took quite as long as the apps of today to load, on hardware that was probably an order of magnitude or more less powerful.)
