All in One Event calendar

So I’m using the All in One Event calendar plugin and while I can use shortcode on the page I want the calendar, and also add separators so the calendar doesn’t bleed into the header menu, I can’t do that for the single events after clicking on them from the calendar. The event’s bleed into the header. There is a field for CSS and I’m assuming that’s the only way around this issue is to insert some custom CSS. If anybody has ran into this please let me know the solution. I was using The Events Calendar plugin, but that uses a page slug and doesn’t create an actual page where you can control layout so I installed the All In One Event Calendar.

The page I need help with: [log in to see the link]
