Hi, please reduce padding numbers in these sections in your theme.scss.liquid file:
media only screen and (min-width: 750px) .featured-collection
(If you can’t find the above, please search for a smaller subtext from the above). the padding is currently 140px and may be reduced to 20 or whatever you think is suitable.
Similarly, for the below:
media only screen and (min-width: 750px) .collection-list
I did not understand the requirement about mobile images. Can you please elaborate or mark something in the mobile view screenshot. Thanks.
