dynamically change height of iframe?

I want to develope a stand alone astore with content of my own like what you can see in the http://shopping.globalinfoonline.com/shop-with-amazon-for-apple-computers-reliable-and-secure/. I want the astore at the top then the content. While using the iframe code,I find lot of gap between content and the products for different displays. It looks awkward for certain pages to have empty space. I want a way to have a responsive iframe or dynamic height adjustment of height so that I can place the astore on the top and my content beneath. With this I will enjoy google ranking for content and feel of stores to the visitors. When products are displayed, the gap between my content and product display must be responsive.
