HA! I got the iframe thing working, and craigsivils, it also works in wik.is.
What you said Steve helped; I had to put the style info in a div tag, and in the iframe itself. This is what the code looks like:
Code:
<div style="overflow: hidden; width: 656px; position: relative; height: 600px">
<iframe id="iframeContent" src="http://deki-wiki/Special:Recentchanges" frameborder="0" scrolling="no" style="left: -210px; width: 800px; position: relative; top: -130px; height: 700px"></iframe>
</div>
And the result is the attached image. Just edit the height and width values until it fits the content you want to show. I'm going to be using this to display the first 2 or 3 lines of a page that contains a {{wiki.anypage("title:User*")}} for a random user section.
The only remaining problem with this is that users are going to click the links in that Recent Changes, and they'll open in the iframe, not the parent window. From what I have researched, the only way to change that behaviour is to modify the link itself with a target="_top".
If anyone can figure out how to have the links from an iframe open in the parent window without modifying the links, I would be ecstatic, as it would also solve my previously mentioned problem with feed.list.
