Sorry once again. I have also searched for hours how to change the size of the gap between the Posts (between right and left post as well as above and below posts).
In the theme editor I found:
.lp-blocks2 .lp-block i::before {
border: 0;
font-size: 28px;
width: 3em;
padding: 1em;
}
is this the right one? But when I change the 3em to 2em, nothing happens. Do I need put something before the code?
