Use -45px until it works.

The problem may be in your settings.
Go to preferences > Common options > Page setup and set all of the margins on the left side to -0.1pt.

This is the CSS to use.

  margin-right: -45px;
  margin-left: -45px;

Jon, this is another test with %

I'm told you, I did.

I did right now:

1 - EPUB to AZW3 in CALIBRE WITHOUT ANY OTHER SETTINGS OR EXTRA CSS.

2 - Calibre give me the AZW3.

3 - Opened the AZW3 with CALIBRE editor

4 - PASTED your code on the top of the main CSS

5 - Looked for any @page CSS\

And the same BUG.

You tried to replicate what I wrote here?


I will look here as you said: The problem may be in your settings.
Go to preferences > Common options > Page setup and set all of the margins on the left side to -0.1pt.


I never changed this settings but I will take a look.

One note - ALL MY SETTINGS WORKS AT PAST.
