Moving this topic to Callisto forum then...
1. make sure that you have latest CI build of Gantry 5 installed
http://gantry.org/downloads#ci-builds
- Do read warning though.
2. Use this code...
body.print-mode #g-page-surround {
background-color: white;
}
To create a custom CSS compatible with Gantry 5 please read this
http://docs.gantry.org/gantry5/tutorials/adding-a-custom-style-sheet
.
Don't forget to recompile CSS from base outline too.
