I specify to my students that their sites must validate. We are using HTML5. The latest change (I don't disagree with it) is that the rel="lightbox' breaks validation. Why is this and can we fix it?
The Adobe AIR application used to be a free download. It was useful because you could edit an ePUB file without needing to unpack it and re-zip it. I used it in my class to show how to edit XHTML and CSS.
