@arminunruh thank you for the solution. This could work indeed.
And let's say I would want two separately scrollable columns, next to the fixed column.
Would there me an 'easy' css solution for this?
The end result would be a fixed first column with text and description, a second column with photos of final result, a third column with black & white behind the scenes.
Most interesting part would be that we would have a full sized web page without a scroll bar on the right side of the screen and that users can separately scroll the 2nd or 3rd column.
Thank you for the input.
