How do I get rid of the scroll bar?

Place your

height 

min-height

style 

iframe 

Just add the below script in Look & Feel->General->Header-Source,
Qualtrics.SurveyEngine.addOnload(function()
{
jQuery("div.ScrollIndicator").css("visibility","hidden");
}
});

In Style under custom CSS add below code: 

* {
overflow: hidden;
}
