>I did a quick scan through my epub css and did not find any fractional values.
The fractional values would be on the xhtml. If you have a Fixed Layout Epub, I'm almost sure you have lots of fractions of pixels.
The issue is pretty apparent if you change pages on an iPad, you can see the letters ghosting to their places. I think iBooks is rounding up the numbers on the go. It looks pretty weird.
I started reading about regex, but I'm not sure how I'd do this. Do you have more experience with them? I have this:
style="position:absolute;top:2542.57px;left:3119.95px;letter-spacing:-1.39px;
How would you write the expression?
Thanks a lot!
