Mark Pilgrim is gone and with him all of his sites and work.
Mark Pilgrim left, but this book still lives on. Unfortunately, now there’s no official resource where people can go to read the book online or download it in PDF format. There are many mirrors of the official site and some PDFs circulating the Web, but they are hideous. They don’t contain original typefaces, the cross-references aren’t clickable, page breaks are in unfortunate places, etc.
Long ago, when Why the Lucky Stiff disappeared in a similar fashion, I saved his Poignant Guide to Ruby and re-published it online. It has since become the canonical resource when people search for it.
Today, I’m republishing Mark Pilgrim’s Dive into HTML5. I’ve also created a beautiful PDF eBook from it:
The eBook has an embedded table of contents, working cross-references, well-placed page breaks and tons of others tiny tweaks and enhancements. It looks great on iPad. I hope you will enjoy it on your device, too.
