Then add the class name fix-container to the ‘Class (wrapper)’ field in the Container stack. If you don’t want a drop-shadow then you can obviously just delete that line in the code.
That is amazing @habitualshaker I thought it may be possible, but was not sure how.
The container is now fixed, thank you!
One small problem - it was behind all other objects, so I have changed the z-index and cured it, but what z-index should I properly be using and where? As you can see, I have simply typed 999 into each section until it appeared on top.
