Very sorry but I think I got confused with grid4 and the background position

With Venture it is actually inside the template

You need to look at the effects tab and background slideshow

Well I've added this code
@media screen and (min-width: 1080px){#sidebar-2, #sidebar-1 {margin-top: 40px;}}
via filezilla - templates - css - custom.css

Sorry this is what I see in the html source code

@media screen and (min-width: 1080px){#sidebar-2, #sidebar-1 {margin-top: -90px;}}So you would add something like@media screen and (min-width: 1080px){#sidebar-2, #sidebar-1 {margin-top: 0px;}}

This is listed in the banner overlay position html

It is in this template style and is affecting the rendering

It shouldn't be there

If you view the source code on this page

websitetester.be/index.php/nl/producten/potgrond

You can see it

it is adding extra space and you see a flash of the unwanted code

It isn't coming from the css it is added somewhere else
