How should I learn Web Development if I'm familiar with object oriented languages like Java and Objective-C?

I wouldn't recommend http://w3schools.com for learning web development. If anyone really does, I would like them to have a look at this http://www.w3fools.com/. Now about answering the question, I am providing few links that are updated frequently and are some trustworthy resources. https://developer.mozilla.org/en-US/learn/html https://developer.mozilla.org/en-US/docs/Web/CSS https://developer.mozilla.org/en-US/docs/Web/JavaScript http://www.webplatform.org/ http://dev.opera.com/articles/view/1-introduction-to-the-web-standards-cur/#toc http://reference.sitepoint.com/css http://www.w3.org/wiki/HTML Now these are the resources to make interactive HTML pages. In order to experiment with these, try installing Firebug and start making edits and view the changes live in the browser itself. In case you get stuck at something, ask questions on http://stackoverflow.com. Good luck.
