I was thinking this too. You <i>can</i> read the HTML and CSS of any website, but there&#x27;s likely no licensing information attached to it. And you&#x27;ll never see the server side code of most websites.<p>What&#x27;s the reason that&#x27;s not considered a problem? Is it because it&#x27;s not actually running on the user&#x27;s computer? Or because you can think of the resulting HTML&#x2F;CSS as output of the program?
