I&#x27;ve tutored a number of introductory CS students and have found w3schools.com to be a fantastic source of reference material for students. Years ago there was some controversy with the site because it taught web standards &#x2F; conventions which deviated (slightly) from the consensus of sites like stackoverflow. Since then they&#x27;ve made a number of corrections and for the most part have really great content.<p>Here [1] is a good discussion on quora on the topic. You&#x27;ll notice that the main complain is out-dated information when compared to MDN. I would argue that MDN is a much deeper source of information that can overwhelm beginners when all they need to know is say, what a &lt;p&gt; tag is.<p>Please please please qualify these kinds of statements when giving information to beginners who can be easily swayed in the wrong direction by well-meaning individuals such as yourself.<p>[1]:<a href="https:&#x2F;&#x2F;www.quora.com&#x2F;Does-W3Schools-really-suck" rel="nofollow">https:&#x2F;&#x2F;www.quora.com&#x2F;Does-W3Schools-really-suck</a>
