Hi there,
The breakpoint is hard-coded into the CSS.
However this is it:
@media (min-width: 560px) {
.wpsp-polaroid .wp-show-posts-inner,
.wpsp-card.wpsp-polaroid .wpsp-content-wrap {
padding: 2em;
}
.wpsp-polaroid .wp-show-posts-entry-header {
display: flex;
flex-direction: column-reverse;
}
.wpsp-polaroid .wp-show-posts-entry-title {
font-size: 1.5vw;
line-height: 1em;
}
}
You may be able to adjust that media query in your child theme to overwrite it, depending on which way you’re adjusting it.
