Considering the following example:
https://ajility.dev/stack-overflow/print-with-bleed/

I would like the gray and blue box to be aligned to the edge of the PDF generated by Google Chrome via the print dialog.

• @page is size: letter portrait or 8.5″ (w) x 11″ (h)
• left-sidebar is height: 11in with a blue background
• intro is height: 2in with a gray background

Why doesn’t this work? Is it possible to prevent the white background from appearing at the top / left / bottom of left-sidebar div?
