Hi there!

Did you mean details of events on the Event listing page?

I have visited your given link, and there was no details though.

Here is sample code you can put in your custom CSS:

.sp-kidzy-event .event-description .details {
    overflow: hidden;
    text-overflow: ellipsis;
    display: -webkit-box;
    max-height: 100px;
    -webkit-line-clamp: 2;
    -webkit-box-orient: vertical;
}

Here, -webkit-line-clamp: 2; you can use the nomber of line you want to show.

Hope this helps anyways.

Best Regards
