If like me you would like to embed iframes from sites such as Amazon Associates then this note might help.
Unlike other sites, Amazon Associates doesn’t offer many options if you want to change the position of one of their advertising frames on your blog. The lack of options for positioning (as well as the actual graphic) can be a little frustrating. I recently asked Amazon Associates for a positioning option and was told
“While we appreciate your needs as an individual, I’m afraid it is not possible for us to provide you with more personalised links. With hundreds of thousands of Associates web sites, we can only provide technical assistance for our tools in Associates Central. We do not offer web design support or HTML techniques beyond the code we provide in Associates Central.”
There is a very simple HTML fix though to position the iframe in the middle of the page
Encapsulate the iframe HTML with a div tag and align to centre the iframe within the web page.
<div align="center">
"the HTML for the iframe "
</div>
