Full Width Author Box

Well never noticed that before - it doesn't actually apply when the Title is above the header....

Try this CSS:

.post-image-below-header.post-image-aligned-center .site-main .inside-article .featured-image {
    margin-top: 1em;
}

That gets the job done, thank you David. :)

Glad to be of help - great to see what your working on!
