events+ calendar shortcode layout width

I have an issue similar to this guy's : https://premium.wpmudev.org/forums/topic/calendar-upcoming-widget-width

But I'm using the [eab_calendar] shortcode, not a widget, like he was..

My calendar is so wide that it is covering up my sidebar.

Could someone point me to the correct CSS to correct this?

Thank you!
