Whitespace-mode configuration or alternative

[Thierry Leurent]

Hello,

I'm not a lisp developer but I'm trying to configure Emacs as a multi purpose 
editor like Atom, Notepad++, ....

In my code, I like to put a comment at the end of a line, for example :
(load-file "~/.emacs.d/A-GPFunctions.el")   ; Load some custom elisp fuctions.
(load-file "~/.emacs.d/A-PLoader.el")            ; Load some usefull packages.
To have a something as sexy as possible, I like align my comments by section.

With whitespace-mode, this lines are highlighted. I don't like this.
How can I change it ?

Best regards,
