HTML5. Read Mark Pilgrim&#x27;s <i>Dive Into HTML5</i>.  And by read, I mean, both the material, <i>and</i> view-source and his stylesheets. The site itself is a tour de force of what he describes.<p>CSS2 and CSS3. The latter is where CSS headed, though it&#x27;s still in development.<p>You can do a hell of a lot of sensible page design with just straight HTML5 and some modest amounts of CSS.<p>Javascript for any automation.<p>CodePen is a great place to play with (and explore for) ideas. StackExchange and Reddit&#x27;s &#x2F;r&#x2F;WebDev and other subs for Q&amp;A with other developers.<p>Maciej Cegłowski&#x27;s rants on current Web faults &#x2F; advertising &#x2F; privacy  <a href="http:&#x2F;&#x2F;idlewords.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;idlewords.com&#x2F;</a><p>There are others who hit this point, and do it well, but Maciej makes a compelling case on all three points (with essays featured here on Hacker News). My read is that the Web is headed for a crisis on the point of design, on many grounds (readability, privacy, annoyances, accessibility), and that, despite much of what I&#x27;ve written above, read Web design may well die. With &quot;Reader Mode&quot; features being included in more browsers these days (Safari, Firefox, Chrome is coming up with it, Opera&#x27;s had it, not sure about MSIE), readers can simply opt out of design. Which may be a Good Thing.<p>Enjoy.
