Title, Description overlay not showing on mobile

Site URL: https://www.mccookchristian.church/moveauction

I tried several custom css codes I saw on other posts, but nothing works. I have an overlay on desktop sites, but nothing on mobile. 

Hi. You mean resize image on mobile?

Well I am an idiot and apparently didn't post the actual problem - can't get the caption/title, description overlay to show on mobile.

Add to Design > Custom CSS

/* show mobile slideshow */
@media screen and (max-width:480px) {
.collection-type-gallery .sqs-system-gallery .slide-meta {
    display: block !important;
}
}
