Greetings!
I am confident I screwed something up in Quick CSS, but I now have the Blog Posts content element forcing the posts’ thumbnail images to display above the title and excerpt and centered, causing a ridiculous amount of wasted whitespace.
Spent most of the day searching here for a solution, and cannot find one, leading me to believe I’ve done something to cause this!
Currently, the page is set to have no sidebar, and I suspect that may have something to do with it, but if I enable a sidebar, the thumbnail image disappears altogether!
Figured it out – had inserted display:none; to remove ‘pencil-in-a-box’ placeholder for posts without featured images.
