7.1 reduce white space around line block

Site URL: https://gar-grouper-xgll.squarespace.com/config/pages

Hi everyone,

does anyone know how to reduce the white space under and above a line (and other blocks)?
Hope you can help me with this issue!
 

Hi,

I can't access your site to see, but try:

.sqs-block-content hr {
 margin-top: 0px;
 margin-bottom: 0px;
}

Or indeed just:

.sqs-block-content hr {
 margin: 0;
}

@ErikaT:  Does the Page have to be public to give you access? (I don't want it to be visible for visitors in this stage)

Thank you for the code. Unfortunately, it improves the white space issue just a little and only above one line.
Here's a screenshot with code and without code:

This is what I'd like to reach:

Hi, if you just make it password protected and share the password here can then take a look 🙂

@ErikaT thanks, you made my day! With this code I could adjust the white space! 😊
(Next time I make it password protected!)
