CCS code for hiding breadcrumbs in Presto Theme

Hi
I am not wanting to disable the breadcrumbs on my pages but I do want to hind them from the public view please. They are displayed on my product but don’t want them to display on any page.

Do have the buttons to enable and disable, but they do not work after adding code from a while ago. So if there is some CCS, that would be great.
Tried a few different ones from other forums but not working.

Theme: Presto

Any help would be greatly appreciated!

Thanks!
Belinda.
