Remove top margin with hidden header

On a certain page, I have hidden the header (logo+navigation etc) via page settings. But now, the page has a top padding of 116 px (probably the height of the regular header).
I see the following code in Chrome Inspector:

media="all"
.html_header_transparency #top .avia-builder-el-0 .container, .html_header_transparency #top .avia-builder-el-0 .slideshow_inner_caption {
    padding-top: 116px;
}

When I change “116px” into “1px” in Chrome Inspector, it looks good, but when I paste this CSS into Enfold Quick CSS, the 11p padding still exists.

Can you help me to get rid of this padding?

Thanks!
