Unable to avoid EPUB to AZW3 extra margins

Marc/o · 06-16-2020, 12:36 AM

Hi, all. I am new to Kindle PaperWhite, relatively new to Caliber and brand new on this forum...

Speaking of margins, I meet the following problem :

Every single EPUB I convert to AZW3 seems to completely ignore any attempts I make at clearing the margins or setting them to 0 :

1) First, under page layout, the four margin boxes are filled with 5pts by default. Whether I leave them to 5pts or set them to 0, or even negative, to trigger the "No modication" value, which is supposed to leave the margins of the original EPUB, I always get the same result on the KindlePW : a margin of a few mm all around the pages of the ebook. Is this normal behavior or something going wrong?

2) Then when I try to fill the Extra CSS box under 'Styling' in 'Look & Feel', the conversion seems to add the right CSS in 0003.css, except the HTML pages do not link to 0003.css, so the styling is not applied to all pages.

My work around for now is that I systematically open all AZW3 files in Edit (T), open the 3 CSS files : 0001.css, 0002.css and 0003.css and add :

body { margin: 0 !important }

When I save and load the books on KindlePW, they are perfect with no extra border around them.

What should I do to avoid these extra manual steps and get it right immediately at the EPUB to AZW3 conversion stage? I found a few similar posts related to left-margin issues on EPUB to Kindle conversion, but didn't find a fix other than modifying the 3 CSS files manually (and repeating CSS, which is bad form, I know, but works in this case).

Thanks in advance for any help.

I've never done body { margin: 0 !important }. dies it override any other margins such as those for offset text or chapter headers?

This line affects the entire body element and the !important rule makes this declaration override any other declarations (providing that one more specific doesn't also have the !important rule attached to it). Other elements inside the body can still have their own margins applied, inside the body box.

Applying this line to all three stylesheets of the AZW3 document (0001.css, 0002.css, 0003.css) seems to solve the margin problem on the Kindle. However, this has to be done manually after the conversion process.

Is there a way to achieve the same result directly at the moment of conversion? I thought it was the intent of the margin boxes or the Extra CSS box in Look & Feel.
