I'm working on a facebook tab that includes an iframe showing content from another website. I've narrowed the iframe down to only showing the part of the website that I want it to and disabled scrolling. In addition to that, I'd like to disable the links in the iframe content, and I've read that it should be possible by adding a transparent .png background image to a div containing the iframe and setting the iframe's z-index to -1, but the iframe is still in front of the image.
So far my css looks like this:
<div class="bgimg" style="overflow:hidden; width: 700px; height: 100%;margin:auto;">
<iframe src="http://www.url.com/site.html" width="1100" height="700" seamless="seamless" frameborder="0" scrolling="no" style="margin-top:-230px;"></iframe>
Keep in mind that z-index only works for positioned elements (can be relative though.)
