Change Syntax highlighting Jekyll

Jekyll use .highlight element in css to highlight syntax. This can be overwritten in your assets/main.scss.

You can then easily use pygments css, modify it a bit to fit to the css code below and all is fine.

It should look like approximately like this:

.highlight {
  background: #282828;
	 color: #ebdbb2;
	 background-color: #282828;
  @extend %vertical-rhythm;

  .highlighter-rouge & {
     background: #282828; color: #ebdbb2; background-color: #282828;
  }

  .hll { background-color: #ffffcc }
  .c { color: #928374; font-style: italic; background-color: #282828 } /* Comment */

I am using here a background color. I add few troubles to find out how to solve this :

I add to overwrite few styles from the code and pre element. I also wanted to wrap the code (white-space: pre-wrap; )

code {
 border: 0px solid #e8e8e8;
 background-color: #282828; // import for the background of the code, even with highlighting
 white-space: pre-wrap; // wrap the code
}

pre {
 border: 0px solid #e8e8e8;
}

Hopefully you is helping you :)
