Adsense plugins not working

When I’m on mobile, as I’m scrolling down, the images disappear and then reappear (I have standard posts with images inserted in them).

Hm, I’d need to test that on my end. Haven’t experienced that myself.

I would like to have small thumbnail images in my sidebar like you have in the live preview. How do I do that?

You would add the “AlxTabs” (left side) and “AlxPosts” (right side) widgets to your sidebars.

And finally, is there a way to make the posts appear 1 by 1 on mobile rather than 2 by 2 so that each post is separated by a line?

Try adding this as custom css:

@media only screen and (max-width: 719px) {
.post-list .post-row { border-bottom: 0; margin-bottom: 0; }
}

Just this, for no border, or:

@media only screen and (max-width: 719px) {
.post-list .post-row { border-bottom: 0; margin-bottom: 0; }
.blog .post,
.single .post,
.archive .post,
.search .post,
.search .page { margin-bottom: 20px; padding-bottom: 20px; border-bottom: 1px solid #eee; }
}
