Some sites require JS because they do weird things like rendering stuff clientside.<p>This site &quot;requires&quot; JS because... The opacity of the article is set to 0? Everything&#x27;s there, everything&#x27;s rendered, but they have a CSS rule (&quot;.use-motion .post { opacity: 0; }&quot;). Only thing I can think of is that they do a JS fade-in or something and missed the unintended consequences.<p>(Speaking of which... Doesn&#x27;t Google penalize sites that have an excessive number of hidden keywords? I wonder if the entire article being hidden qualifies...)
