How would I pass an entry URL to an iframe in a template? I'm trying to showcase some responsive code and would like to create entries just with that code example. I would like them to appear in a template that has some js to resize an iframe and show responsiveness of the entry.

Any thoughts on how I can accomplish this?
Load the entries into a div then create several buttons to change the width of the div, or use JS to resize the div. Thus showing your users what happens to the responsiveness of the design at different widths. It doesn't need to be a iframe. Or just send them to a template with a UI element showing them to resize the browser.
