Hi Julia!
Thanks for reaching out to us! Let me try to help you with that topic.
First, please note that we are limited in how much we can support custom development questions like that.
That said, we always like helping out and at least point users into the right direction as best possible.
I did find a way to achieve what you are looking for with some custom CSS. Try copy and pasting the following styles into your theme’s styles.css file, or by adding them via the WordPress customizer by going to your wp-admin > Appearance > Customize > Additional CSS
.fusion-blog-layout-grid .fusion-post-content-container {
margin-top: 20px;
height: 150px;
overflow: hidden;
}
#wrapper .post-content h2 {
white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis;
{
Bear in mind this will hide part of the event title as well as the event excerpt, so it has some side effects that you might want to consider.
I hope that helps! Let me know if you have other questions.
Best,
Victor
