Hy, as soon as I use a “Farb-Sektion” or a “Grid Row” above the first element on my side, which is a “Einfacher Slider” the “Farb-Sektion” or the “Grid Row” breaks out of the layout, on the left side.
Can you post a screenshot of the issue please? I checked your website but could not see any issues.
You can upload your screenshots on imgur.com or Dropbox public folder.
