Hi Gregg!

I’m assuming that you want to add a background effect to an entire post/story. If my assumption is wrong, please let me know what you’re wanting to do exactly.

You can add a background image by writing some custom CSS code, like:

/*** FOR THE POST BODY***/
body .jorgen-entry-content {
  background: #FFFFFF; /*USE THIS TO CHANGE THE COLOR*/
  background-image: url('http://i.imgur.com/chDA7UY.png'); /*USE THIS TO ADD A BACKGROUND IMAGE*/
}

/*** FOR THE COMMENTS AREA***/
body .jorgen-comments-wrap {
  background: #FFFFFF; /*USE THIS TO CHANGE THE COLOR*/
  background-image: url('http://i.imgur.com/chDA7UY.png'); /*USE THIS TO ADD A BACKGROUND IMAGE*/
}

/*** FOR THE PREVIOUS/NEXT STORY NAVIGATION***/
body .jorgen-story-pager {
  background: #FFFFFF; /*USE THIS TO CHANGE THE COLOR*/
  background-image: url('http://i.imgur.com/chDA7UY.png'); /*USE THIS TO ADD A BACKGROUND IMAGE*/
}

You should always put custom CSS in an external plugin. When an Aesop theme is updated, any CSS you add/edit in the core files will be erased, and we certainly don’t want that! 😉 Please use a plugin such as Simple Custom CSS (https://wordpress.org/plugins/simple-custom-css/) and add your custom CSS there instead.

Hope that helps!
