I've had problems peculiar to CoolReader in the past. In each case it had to do with first line in the stylesheet similar to this:
@namespace h "http://www.w3.org/1999/xhtml";
You might check to see if this could be it. CoolReader was the only reader that I know of that had a problem with that line of code. I removed that line of code and all was right with the world.
