Hello,

 

I have problem with my background image URL.

 

My directory struct it is a follow:

 

          ->Assets

               ->  css

                     -> siteB

                           ->SiteB.css

               -> Images

                     ->example.png 

 

 

When I am develop is work fine with:

          background-image: url('../../images/example.png');

 

But when publish the project and run in IIS only work with:

           background-image: url('../images/example.png');
