CSS for Catalog widgets set to Calendar to Default to Agenda

Hello I need a very smart person to help us out. We have put a catalog on the page and set it to calendar view. It produces the calendar and is very hard to read -- especially when trying to get a quick at a glance view of the upcoming webinars for the month. I’d like to use CSS to change the default view from “Monthly” to “Agenda” right now each person has to manually change the setting themselves. 

Has anyone already figured this out that could share their CSS?
