I have a forum application that i need a customized css code to expand the replies in my forum

Hey I am new to this thing but have dabled in BASIC coding for what it is worth.

I am putting together a website for the first time through WIX. There is a forum application( Social Forum ) that I am using to communicate with my members. The forum works fine but the replies to each discussion are closed by default and I have to go through each reply and click it to open it. My goal is to have all the replies open when I open the topic.

The app , Social Forum, has an input where I can use customized CSS to modify the application but I dont know what I need to change to make this possible.

I will attach the apps default code and if someone can tell me what to change so that the replies are open by default I would be forever in your debt.

Thank you so much for taking the time to read this and if you can help I would REALLY appreciate it.

Thanks again!
