Where is the active line background color of atom editor?


 Because I set a background image for the atom editor, some codes cannot be distinguished from the background. Thus, I want to add another frame of background only for the texts. 
 
Solution is :
 
 

Try this:

 

atom-text-editor::shadow .lines .line.cursor-line {
  background-color: /* color */;
}
