Here is the CSS from the ePub version with a few changes. I removed the font size that makes the body text small. So now it's the default size. I added in my body style, and I removed the Widows and Orphans of 2 since my body style has them as 1. Other then that it's the same CSS.

font-size: 0.83em; as shown int he CSS snippet above is really annoying as it makes the base font size smaller. That means then having to adjust your font size and then when you open a new book that has the 1em font size, having to change it back.

So here is the CSS code you could try in the KF8.

body, div, dl, dt, dd, h1, h2, h3, h4, h5, h6, p, pre, code, blockquote {
  font-weight: normal;
  font-style: normal;
}
body {
  widows: 1;
  orphans: 1;
  margin-top: 0;
  margin-right: 0;
  margin-bottom: 0;
  margin-left: 0;
  text-align: justify;
}
