change font in Campaign detail page

Hello,
I need to change the font on the default campaign page in order to make it suitable with the webside (specifically the font used for numbers and donation details). I am not particularly expert in css so I do not really know where to begin with.
Please help,
Isabella

This is the page:
www.amaleducation.net/pubblicazioni/crow...un-passo-avanti-2019
