CSS floats are extensively used in our primary source encoding, and they're now no longer really necessary in many cases (such as forme works). They also cause problems for the PDF generation. I've started a process to remove them, processing away all the right floats used for catchwords. So far the results are pretty good. I'm next going to look at running headers and page numbers. The code was a bit tricky because in some situations I needed to flip the order of forme works, and in others not. 180 minutes.
