Hi,
I really prefer to read black on white and not on grey. For some reason the news epub created from taz.de (die tageszeitung) with the Calibre recipe creates a grey background.

How come? I took a look into the recipe, but I couldn’t find out any instruction that asks for a grey background. Maybe the author of the recipe didn’t even intend it. After unzipping the epub file I could inspect the generated CSS. There are two background colours defined:
Code:
[…]
.sect1 {
background-color: #efede4;
[…]
}
[…]
.calibre6 {
background-color: #ccc;
[…]
}
[…]
How can I get rid of the grey background? Ok, I can create a new recipe, actually I did a very basic one that just includes the RSS feed URL and yields a white background. But where in the included recipe is the instruction for a grey background hidden?
