Image padding on Mobile - Brine Template

I need some help fixing extra padding in between two images on Brine when viewing on a mobile device. 

The code I am currently using is: .

@media screen and (max-width: 640px) {
    .homepage .sqs-block.image-block:last-child {
        padding-top: 0 !important;
    }

Although I know this is only targeting the homepage. How can I target my services page (https://www.domaniquejazmindesigns.com/services) as well to get rid of the extra padding in between the two image blocks at the bottom of the page when viewing on mobile?

1. Target Pad ID. https://beaverhero.com/squarespace-how-to/#How_to_Find_Page_ID

2. Remove padding

Add to Home > Design > Custom CSS

@media screen and (max-width:640px) {
div#block-yui_3_17_2_1_1571906209264_4602 {
    padding-bottom: 0 !important;
    padding-top: 0 !important;
}
}

Thank you! I'm checking out your link on targeting the ID right now 🙂

Gah. Still not working for me for some reason. Huge gap at the end of every section on the mobile version 😞

the padding % value changes how close together they are

@media screen and (max-width:640px) {
/* remove absolute */
.sqs-block.image-block {
    padding: relative;
}
.sqs-block.image-block {
  padding: 0%; 
}
.sqs-layout .sqs-row .sqs-block:first-child {
    padding-top: 0px !important;
  padding-bottom: 0px !important;
  }
  .sqs-layout .sqs-row .sqs-block:last-child {
    padding-top: 0px !important;
  padding-bottom: 0px !important;
  }

First of all. Thanks a lot for getting back to me. I embedded the code at 0px and it made no difference sad to see. It looks great on desktop (first screen shot) but mobile is terrible (second screen shot). Screen shots below for the first block. 

Appreciate the ongoing support

Could it be because of the shape of underlying image (just a guess) ?

not sure, I replied to your email. I'm no expert on this though. But looks like you've got some pretty big padding and/or margins going on, and not a stacked column structure, which the code is intended to target.
