One of the shortcomings of the Black-Letterhead theme when it first came out was, there was no spacing between the images and the text. I’ve added margins of 7px around the images located in the post section. Notice, there is now spacing between this Fantastic Four image and this text.
The change is cosmetic, but it makes a big difference to the layout and presentation. To add space around the images, edit the “style.css” file located in the Black-Letterhead directory and use the code below.
I also like how Aitortxu has done here.
