[html] How to center-justify the last line of text in CSS?

There doesn't appear to be a way. You can fake it by using justify and then wrapping the last line of text in a span and setting just that to text align center. It works ok for small blocks of text but is not a useful approach to large quantities of text or dynamic text.

I suggest finding somebody at Adobe who's involved in their W3C work and nagging them to bring up right/left/center justification in their next meeting. If anyone's gonna be able to push for basic typography features in CSS it'd be Adobe.
