remove grey area

Is it possible to remove the grey area of pages in Shapely? See http://www.vaardigleven.nl/over-vaardigleven/ as an example. I would like to remove the grey area in total with the title… I’m looking forward to your reply

hey there

Hope you are having a good day and thank you for your question
