Hi Nikko,
Thank you so much for contacting me so quickly. This is one thing I like on Kriesi.at! and I’m not angry anymore. ;-))

I’ve solved the problems with color sections, by using the following code, I found somewhere here in the forum:

.template-page.content.av-content-full.alpha.units{
margin-top:-50px!important;
padding-top:0px!important;
}

The remaining problem is the spacing of the columns. I cannot close these gaps. The similar command I used for the color sections might help, but I didn’t find the CSS classes of the columns. That could be a temporary solution. I have not yet checked on smaller screens.

Don’t hurry, it’s half past 11 p.m. and I stop working for today.
Regards
Peter
