The key attributes (and text) that you modify set variables embedded inside of BoxPress’s two CSS files—blog-main and blog-extra. These are the CSS stylesheets found in the CSS container note at the root level of your TBX.

• blog-main: The core styles are inside blog-main. This stylesheet is in fact a modified version of the stylesheet used for the Blog example on the Bootstrap website. Among these modifications: Tinderbox export code that inserts attributes from dashboard notes.
• blog-extra: The other stylesheet-note, blog-extra, contains code for special objects, like the Tinderbox note mock-ups, inserting attributions to quotations, tool-tip formatting, media formatting, modifications of standard elements, and margin fixes.
