I had 4 collections on my homepage collection list and I was trying to figure out how to show 2 rows with 2 collections each on desktop instead of the default of 3 collections on 1 row and 1 collection on the second row. I couldn’t find the answer on these forums so I decided to post my solution here because I know other people have had the same problem.
Go to this section (use ctrl + f) in assets/theme.scss.liquid and change min-width to 50%:
@include av-mq(‘desk’) {
.CollectionItem {
/* added, changed from 33.33333% */
min-width: 50%;
}
