Remove URL

Hello all,

I was wondering if it is possible to remove the automatically generated URL’s above all the content.
I’ve tried some CSS but I am probably doing something wrong, I tried:
#pf-src {display: none;}

And I still have “Beschrijving” in the Print display, even though it isn’t shown on the site.

Any help is much appreciated 😀
