But there are some rules that work.
Keep the base font size at 1em and offset text as well.
Do not embed a rubbish font to replace the base font.
Do not embed any fonts that does not look good on eInk.
Do not waste too much space for the chapter header.
Do not set right/left margins.
Do not set a line-height.
Make the code streamlined so there is less chance of a problem.
If you do use a program that generates rubbish code, hand fix the mess you made.
No paragraph spaces.
Proper indents not to small or too large (I prefer 1.2em).
Use em and not px, %, or other measurement where appropriate.
No colored text.
No background image or color.
For offset text, use a proper <blockquote>.
For a standard paragraph, use a plain <p>.
