Q:

I am using CSS to hide radio buttons, but I would like to display them on one page using Javascript

On Qualtrics, I have entered the following CSS to hide radio buttons in the entire survey:
input[type=radio]{
visibility: hidden;  
}

However I would like them displayed for one page.  I can only use javascript to do this.  
Is it possible? 

A:

No need to add the jQuery library.   Qualtrics uses prototype.js and you can use that.   Just add the following JavaScript to the first question on your page:
Qualtrics. SurveyEngine.addOnload(function() {
    $$('input[type=radio]').each(function(obj) {
        obj.style.visibility = 'visible';
    });
});

The code finds all the radio radio buttons on the page and changes them to visible.
