You can see the the width of the background image doesn't make it as far as the nav bar.

Answer 1

I think your problem might be the default margin or padding on the html and body tags. Try:
html, body {
margin: 0px;
padding: 0px;
}
Not sure if that will work, but it's worth a shot.

Answer 2

The reason for this is bootstrap's container class, that takes up padding on both the left and right hand side. If you remove this class, the image will take up the full screen.
Or, you can use the container-fluid class
Bootstrap requires a containing element to wrap site contents and house our grid system. You may choose one of two containers to use in your projects. Note that, due to padding and more, neither container is nestable.
Use .container for a responsive fixed width container.
Use .container-fluid for a full width container, spanning the entire width of your viewport.
I tested it out in Chrome's Developer tools, and that fixed it.

Answer 3

it is due to you have added class container remove this class from first div it will resolve you issue.
<div class="container special"> to <div class="special">
