Saved tiddler as HTML/text, tried some CSS styling, inline stuff, etc. Searched around everywhere to no avail. Finally inspected and came to conclusion it was maybe td-border stuff.
It seemed like I randomly tried one thing that worked. It was something Eric Shulman had from another unrelated post that I can’t find anymore, but contents subsequently disappeared because I hadn’t figured out yet about saving to HTML/text.
This is the entire tiddler! Set to HTML/text. I have a server that is serving a collage of random pictures as an HTML page for source. No, padding, margin, float left, etc. As said there was one working instance found, but…
But in your image, it seems to be a tiddler holding the iframe call. So, again, it would be easier to help you if you could post the actual tiddler with the call so that one can use the inspector tool to investigate it. Does the same thing happen if you apply your code on tiddlywiki.com ?
