While converting from MS Word, I have noticed extra css (styles=Class), while styles are not needed but it adds automatically.
In MS Word I made default paragraph and style may be around 5 or 6. But while converting to epub it took around 40-50 styles.
How it can be reduced? and I want to change fonts for all styles(I means Calibre class 123..) how can I do it in calibre at one go? I use sigil too.

Thank you
