Adjust padding between featured image and heading

Hey there.

Thanks for the great theme. A while back you gave me a child theme coz I wanted the H1 title on top of the featured image. Now, my issue really is cosmetic. If you look at the above page, there is really little padding between the second title, “How social media is affecting the world of marketing” and the featured image. Would be great if it was there.
