Line padding

Site URL: https://fireflyfuture.squarespace.com

Hello there, I am having trouble with reducing the padding around the lines. I've chatted to SS chat and they can't help me with the CSS and hoping I might be able to get some help here. 

//reduce line padding in table//
.sqs-block-horizontalrule {
height: auto !important;
padding-bottom: 0px !important;
padding-top: 7px !important;
position: relative !important;
}

This works when I have CSS edit open but when I hit save and refresh my page it goes away 😞 Any help would be greatly appreciated. 

I found this worked***

 

.sqs-block-content hr {
 margin-top: -10px !important;
}

.sqs-block-horizontalrule {
 margin-bottom: -30px !important;
}

if anyone finds the above, this worked for me

.sqs-block-content hr {
 margin-top: -10px !important;
}

.sqs-block-horizontalrule {
 margin-bottom: -30px !important;
}
