Don>I would assume PG must be doing something like this now for html files for ereaders. If you know an html file is going to an ereader format, and you know the default css has, say, irrational margins, you adjust the css. It's what css is for. Isn't that currently happening? Especially for DP books, the pseudo-standard css would I'm sure have default adjustments that would work in most cases. Not really what is currently happening, and epubmaker adds its own tag-on css file, but I can't really figure out how what is in there got in there, because it doesn't make a whole lot of sense to me. Some people at DP understand small machines, and implicitly write to those machines, and other people at DP say PG says they want HTML so what I will write to is the copy of Moz I have on my PC as it displays on my 20" monitor. And people read books about how to make fixed layout HTML home pages and then assume that what they read there represents "good" HTML practices for writing books.
