Reply To: Perfectly align graphics behind single lines in a text

I would use IndyFont Pro to make a font containing a single character (that wide bar that you want to use for the background). Then use that character as a bullet in a paragraph style. All you need to do to add the wide-bar-bullet is to specify that paragraph style, with some sort of white space. To get the subheading to sit directly on top of the wide bar bullets, you can either really tighten up the leading in the SubHeading paragraph style, or you can adjust the wide bar character in your font design to have it sit really low on the baseline.

You may even be able to apply the wide bar bullet to the actual subheading paragraph style itself, although that will take some more fiddling.
