Hello this should do the trick, into your custom css :
.single-container { box-shadow: none; }
It deletes the shadow around your image, since your image has a white background and you website too, there is no need to delete the margin, hope it helps
Hello, if you are still looking for a solution here it is, put this into your custom css :
div.post-header, .post-excerpt {
display: none;
}
Hope it helps
