How to choose font size for event description? 
Hi there, @Jonas_Svarholt and welcome aboard 
We agree that it would be great to have a setting to change the size of the description text. If more users upvote this idea, we’ll try to consider this opportunity in the future.
As for now, you can use this code in the Custom CSS field on the Style tab of your widget’s settings 
/* Event Card */
.eapp-events-calendar-description-component {
font-size: 16px;
}
/* Popup */
.global-styles,
.eapp-events-calendar-popup-item-description {
font-size: 20px;
}
Friends, great news: this feature request is in the Design stage now!
We’ll keep you updated on the progress
