Hi Erich,

I have provided the custom css codes you can try below.

#es .es-side-widget__event a.es-side-calendar-date__title {

    white-space: nowrap;

    overflow: hidden;

    text-overflow: ellipsis;

    width: 90% !important;

    display: block;

}

I do recommend that you display the whole title because users may be turned off since they are not able to see the whole title.
