Hello everyone!
I would like to set up a true "Visual Analogue Scale" in Limesurvey. I am using the slider with a minimum number of 0 and a maximum of 100. 
Now I  need the numbers above the slider to disappear. I have read to edit the custom.css with the following function:
.slider_callout { 
    display: none;
}
My problem is, if I use that function and add "slider_callout" to the css class of the question, the whole question disappears and not only the the numbers above the slider.

Does anyone know how I can make this work?

Thank you very much

 

Hi,

1.and add "slider_callout" to the css class of the question

This is an absolute misunderstanding.
If you add a class here it affects the question. And you say "display:none". So the questuion is not displayed.

And you read this

I have read to edit the custom.css with the following function:

So, do it.
BUT you should use the correct class name.
Nowadays it is
