This goes back to my argument that a responsive template should be responsive to screen size on page load and on viewport resize.

reload the page.

You want people to reload the page when they turn their tablet from landscape to portrait?

hey: I love this argument ;-)

I also have the problem, that the tooltip is empty. When rescale the page ==> reload it ==> rescale the page again ==> tooltip is visible.

I'll add the on resize/change orientation event.
Tony found a good argument, so he just let me no choice ;-)

LouisGac +1 :)

In fact : RWD don't need javascript ....

@DenisChenu, yes of course, in most cases CSS media queries should do the trick. However, I think in this case (and certainly in others) the labels aren't being rendered at the higher screen widths so there is nothing to apply the CSS to.

Tested:

@media (max-width: 768px) {
.table.question .hide.label-text{
display: block !important;;
}
}

Need some other css maybe (.no-more-table maybe for example)

I think a nice solution would be that the core views don't use anything like .hide but use the default bootstrap classes.

I solved this for the array/array question type by using visible-mobile and visible-desktop. Maybe someone can do something with it:

There are an issue in bootstrap with "sr-only visible-xs-block" : the sr-only put outscreen, the visible-xs update only display.
