Background Ad on Retina Display

If I put the background advertising on my Retina Display of your MacBook Pro can be seen as well -> http://185.17.107.54/sitonuovo/

This is the image background -> https://dl.dropboxusercontent.com/u/22334399/homepage.jpg

fix, but by resolution 1199px to 1019px don’t consider the command that I put in the responsive Visual 1024px +

This is the command:

.td-header-container {
padding-top: 80px;
}

.single_template_6 .td-header-container {
padding-top: 0px;
}

Why?

Solved.

I put this code in Custom CSS

@media (min-width: 1019px) and (max-width: 1199px) {
.td-header-container {
padding-top: 80px;
}
}
