Change height of days in calendar with CSS

Hi guys,

Im trying to change the height of days in the calendar with css, but so far i've been unable to make it work. I can locate the setting if i inspect the page in chrome, but i havent been able to make the custom css work.

I've tried with, among others, this:

#view_185>div.knack-calendar.fc>div>div>table>tbody>tr.fc-week0.fc-first
{min-height: 80px !important;}
