Style questions

Hi,

How do i change the style of the paging numbers below the events?
They are too small for mobile devices now. I like it to be larger and in a block with a color..

And.. any idea how this happens: when i click on a day in the calendar (in the sidebar) the style of the calender changes. I don’t want that..

Look at: https://culturavenray.nl/agenda/ for my eventspage.

Many thanks!
