Thank you for your reply. I don’t see where I can change the thumbnail of the post. I can only change the featured image, which need to be vertical for the layout.
Add this in your css:
@media ( max-width: 768px) {
.archive-post-header {
position: absolute;
right: 0;
bottom: 0;
left: 0;
padding: 10px 30px;
background: rgba(0,0,0,0.75)
}
.archive-post-title {
font-size: 1em;
}
.has-post-thumbnail .archive-post-header, .has-post-thumbnail:hover .archive-post-header {
bottom: 0;
}
.has-post-thumbnail .post-overlay {
background: transparent;
opacity: 1;
}
}
