Sorry got busy with updates and upcoming HTML version of the theme. I saw the issue earlier and initially thought having bigger text title seemed to fix it. But that’s not always possible as in your case and here is a better one for you which should work even if titles are varying in length –
Paste the following CSS into Custom CSS panel in theme options panel –
@media only screen and (min-width: 480px) and (max-width: 767px) {
.image-grid .threecol:nth-child(odd) { clear: left; }
}
Beautiful site. I see that you do not have thumbnails set for some of the blog posts. If you want to retain it that way for a few posts and have thumbnails only for selected ones, have this piece of code in Custom CSS outside of above one to make borders appear on the top.
.post-snippets .hentry .entry-text-wrap.nothumbnail {
border-top: 1px solid #DADADA;
}
Let me know if you need additional help. Thanks
