Error in azw3 books with reduced margins after conversion with Calibre

[mg10]

Hello
I'm not sure if this question should be asked in this forum. If so, please, let me know the best one.
This is a problem that appeared after converting from epub to azw3 with Calibre adding a css entry to reduce left and right margins. This works fine on my Scribe but not on my new PW11 after upgrading it to the latest firmware version.
After the upgrade, started some errors when opening or moving inside the books. If I don't include the code in the css page the converted book works fine but again appear the huge default margins.
The used code is:

html {
margin-left: -45px;
margin-right: -45px
}
And the error that appears in the books:
"An error occurred. If you purchased this item from Amazon, delete the item and download it from the Cloud."

Do you think it's a bug in the new firmware or can the code be modified to fix this behavior?
Thanks

If the kindle doesnt like negative margins there's nothing calibre can do about it, other than stripping them out.

Thanks kovidgoyal
It's what I was afraid for... Let's hope this firmware change isn't here to stay...
Thank you for your work with this great tool

Kindle PW5 with the latest firmware and negative margins work. This is the CSS code I use. I put it at the top of the CSS.

html {
  margin-right: -45px;
  margin-left: -45px;
  break-inside: avoid !important;
}

Try -1.5%

Are you putting the negative margins in the ePub CSS and then converting to KF8? What I do is convert to KF8 from ePub and then edit the KF8 to add in the negative margins at the top of the main CSS.

It's not % vs px. It's something else as the code I posted works for me.

Possibly true. Though never seen negative margins fail on USB transfer. Ages since I've use the "Send to Kindle" service which IMO is best avoided.

We'll just have to wait until the OP comes back and properly describes what is being done.

Hi All
Returning to this topic...
With my Scribe I'm using this option in Calibre (styles --> additional css), when converting from epub to azw3, in order to get desired margins:

html {
margin-right: -130px;
margin-left: -130px;
break-inside: avoid !important;
}

After updating a PW, I could see that this option caused an error when opening the book, or trying to change fonts: the one I indicated at the beginning of this thread:
"An error occurred. If you purchased this item from Amazon, delete the item and download it from the Cloud"

In order to avoid this behavior with my Scribe, I stay on an old firmware version because don't know if this error is going to be repeated in the Scribe.

My question is: can someone who has 5.16.6 release or latest, confirm if this happens as well? Someone who uses Calibre and transfers the books through it. I'd like to avoid upgrading if I can no longer use the margins I like, because I won't be able to downgrade it.

Thanks in advance

Well, sorry, because I repeated this topic in Kindle forum and it seems it's nor permitted.
Regarding solutions, I was testing with upgraded PW and got the same results.
Tried with percentage instead of px, and works just several pages steps, but when you change font type and move among pages, the error appears.
In my Scribe with 5.16.2 firmware, this doesn't happen. I'll keep this version until be sure that with latest firmwares this behaviour doesn't change.

Hi JSWolf
My PW Signature with latest firmware gives this error in converted books with negative margins:
"An error occurred. If you purchased this item from Amazon, delete the item and download it from the Cloud"

The error appears mainly after return to another book. Since that moment, the error doesn't allow pages to go forward or backward, until is restarted.

Please, is it possible to move this thread to Kindle Developer's Corner? I think it fits better there and will be more active. Thanks

I add that code to the KF8 eBook using the editor. I do not convert with that code in place. It works that way. So you have to go to the editor and add your code at the top of the main CSS.

I test It: convert epub to azw3 with default settings on Calibre and no extra CSS, and after converting, edit the azw3 adding the CSS code. Then transfer it to pw. Apparently it works when paging after opening the book first time, but once I change to another book and return to this again or after several movements of pages it starts failing. It's frustrating. Are you using it with latest firmware?
