I’m creating posts on Github pages using a Jekyll theme. When I use three back ticks for a short code snippet it puts a box around the code. Instead of having the box I’d like to change the background color of the code. I’m new to Jekyll.  
Here is a section of my \_config.yml:

> markdown: kramdown  
> highlighter: rouge  
> plugins:
> 
> - jekyll-sitemap
> - jekyll-paginate
> - jemoji

Any help would be appreciated!
