Title: Fix chrome canary error in salvattore example

If the 'display' of [data-columns] is set to 'none' the content value of the before element is empty. This leads to an error. Fix done by making it visually hidden. Change to documentary necessary also, not done here.
This references #40 and maybe #38 too.
