You may have noticed that one of the best websites for learning HTML5 suddenly went dark a little while ago. Apparently the author, Mark Pilgrim, decided to exit the internet and took all his writing with him. And this meant that he marked the site Dive into HTML5 as 401-Gone. I was disappointed both because it removed a valuable resource and because I loved his “The All-In-One Almost-Alphabetical No-Bullshit Guide to Detecting Everything” Which made it easy to quickly detect whatever HTML5 thing I wanted to detect, without having to memorize it myself. I wasn’t terribly upset, as I bought a copy of the book version, HTML5 Up and Running in eBook format long before I even knew of the website. But it was still a loss for anyone else wanting to learn HTML5.
So when some html5homies put it back up at http://diveintohtml5.info/ I was very happy. This is very good news. And what’s even better is that they are going to continue to add to it to keep it up-to-date and accurate.
