Well, let me jump in here too. Just relearn HTML, JavaScript, and CSS = HTML5. I therefore recommend two books:<p>JavaScript for Web Developers and CSS3 The Missing Manual. Don&#x27;t overthink this. From this you can move on to frameworks if you feel you need them.<p>Now, concerning the backend ... well, lots of choices. C# with ASP MVC, Ruby, JavaScript with NodeJS, PHP is still very relevant. Pick what you like, seriously.
