White space between rows

Please add to your custome css this code:

#pg-144-0, #pg-144-1, #pg-144-2, #pl-144 .panel-grid-cell .so-panel {
    margin-bottom: 0 !important;
}

It worked for the first row but there’s still a tiny bit of space between the blue row and the grey one below it. Do I have to have custom CSS text for every row I make?

Please, replace previously css code to this:

#pl-144 .panel-grid-cell .so-panel:last-child {
    display: inline-block;
    margin-bottom: 0;
}

Now all should works fine.

That actually separated everything even more than the last code…

I noticed “child” in the code but I’m not sure if this is a child theme or not. Thanks for helping me to resolve this btw it’s really appreciated!!
