Fix CSS for Chrome PDF Print

[d6y]

As of today, File > Print from Chrome produces the best looking PDF. If we include this in the template:

gnab/remark#50 (comment)

We also need to disable animations (these appear as blank pages in the PDF):

@media print {
  * {
     animation : none !important;
     transition-property: none !important;
  }
}

works very well for me, except that the code blocks are empty when Printing to PDF (but rendered on screen) when I use some fonts like Ubuntu Mono 👎
UPDATE: one should tick the box 'Background graphics' at export!
