Hi there,
you can either change your Mobile 2 column CSS so they don’t effect the WPSP Cards like so:
.wp-show-posts-columns:not(.wpsp-card) .wp-show-posts-single {
display: block;
width: 50%;
}
or you can force the card image square and reduce the content padding:
@media (max-width: 768px) {
.wpsp-card .wp-show-posts-image img, .wpsp-card.wp-show-posts-columns .wp-show-posts-single .wp-show-posts-image img
{
width: 100%;
}
.wpsp-card .wpsp-content-wrap {
padding: 20px !important;
}
}
