Hi Tony The issue here is some arcane details of how HTML and CSS work, and how they interact with TiddlyWiki.
HTML documents contain text and tags. The text can contain any kind of whitespace. Browsers ship with default stylesheets that assign styling to tags and combinations of tags. In particular, the standard CSS for ordinary text collapses runs of whitespace into a single space, regardless of whether it is made up of spaces, newlines or tabs. That means that the whitespace in an HTML document generally doesn't matter, and an author can use whatever whitespace conventions work well in their authoring environment. Now, browsers support a method "textContent()" on tags which retrieves the text of the tag and any descendent tags. The text will faithfully contain the whitespace in the original HTML. So the fundamental problem is that the display of your tiddler is governed by CSS, and not by the whitespace within it. But, when the wikify widget is used with "text" output, it uses that same textContent() method to retrieve the text portion of the HTML. That means that you get the whitespace contained in the original HTML, and not the whitespace "generated" by CSS for display. The dichotomy between rendering to dynamic HTML and rendering to plain text is embodied in the details of how we use TiddlyWiki in the browser to generate an interactive document while also using it on the server or the browser to generate an HTML file for a browser. The nub is that when you're extracting text content then whitespace matters.
