We have success! Hurrah \o/
This is actually really interesting, I hadn't realised that you could
assign the 'click' to the holding div and it would be applied to the
elements below it.

Thanks for this T.J. It's quite fundamental to a number of parts of
what I'm working on so I'm pleased to have found a solution and learnt
some new tips and tricks along the way.
Thanks also to Alex for his help and perseverance, and to Walter too.
