Hide Preview/Intro Text in Posterboard View

If you want to hide them, create a child theme and hide them with CSS https://support.time.ly/creating-a-child-theme/ otherwise you have to modify the behaviour of file posterboard.php

Thank you for responding! I followed the instructions on the link you provided up to creating an override.css file.

Will you please help me out a bit more by showing me what code to use to not display preview text in posterboard?

I’m stuck. How do I know what code to add in my override.css file so that my posterboard does not display preview text from the event description?

After some research, I came up with the following:

.ai1ec-posterboard-view .ai1ec-event-description { display: none; !important;}

Should this work? I’m still a beginner and appreciate any help!

Yes that should work.
