White background in the right side

Hi!

I don't know what I did but I have a white background in the right side on my site.

Hi there,
please disable the booking module and it should work.
If yes, you know where the problem is.

Hi!

I had already tried to disable all the modules but the problem persisted.

The problem was this code into custom.css:

@media (max-width: 768px) {
#menu-outer {position: relative !important}
}
.main-outer, .top-a-outer, .footer-a-outer, .top-b-outer, .top-c-outer, .top-d-outer, .bottom-a-outer, .bottom-b-outer, .bottom-c-outer, .bottom-d-outer {
padding: 40px;
}

Thanks!
