Hi,
I'm an absolute beginner, and I literally don't have a clue about html and css.
I've converted a bunch of InDesign files to ePub, and everything looks fine except I realize that the spacing before and after paragraphs are almost non-existing in the ePub.
So I'm looking for a fast and easy way to add some extra space, preferably by
cheating so I won't have to learn anything about ebook editing.

(Not just because I'm lazy; I've only got this one book and I'm never ever going to write another, so it's just not worth it to spend too much time.)
I found out that it's possible to simply add a <br> in the code whereever I want an empty line (that won't make the entire file explode or something, will it?), so that's an option if everything else fails.
Only thing is I need to do it like a thousand times, so it would be really nice if there were some kind of automated way to do it. Also, a full line is a bit over the top; something like 3/4 line or so would be perfect...
Thank you in advance for any hints or suggestions!
