Event Organiser

I customising the full calendar in Stephen Harris excellent ‘Event Organiser’ plugin.

I’ve disabled the ‘Event Organiser’ front end css and all is going well with the exception of the ‘prev’ and ‘next’ month buttons. I trying to replace these with ‘genericon’ arrows but just can’t seem to target them in my css.

Been able to edit all other templates in this plugin, but this has me stumped!

Hoping somebody may have done this and can point me in the right direction.

I’m working with Twenty Fifteen, using a child theme.

Thanks Ant
