Disable Previous Button in Survey

I would like to disable the previous button in a MaxDiff exercise. I've been able to figure out how to disable the browser's back button, but is there a way to disable people from going backward during the study?

You're going to use some CSS (cascading style sheets) code to disable the previous button in a survey. You can place this code anywhere within the question text (to eliminate the button for that page only. If you want it not to appear throughout the entire survey, then place the code in the Survey Settings > Headers and Footers > HTML Head Tag section.

<style>#previous_button {display:none;}</style>

Or, in version 7:

<style>#previous {display:none;}</style>

Or, the following CSS code will also remove the whole div:

<style>div #previous{display:none;}</style>
