Hi Glenn,

Yes, I would agree… except that I have no exposure to CSS or to the process involved in changing / extending it.

My proposal is simply meant as a statement of desired functionality… I defer to those with better understanding of the supporting technologies to consider how it might be implemented. I accept that it is likely ☹ that the (correct IMHO) choice by TTWG of CSS / XSL:FO as referenced standards may mean that my ‘shrink to fit’ desires are not possible. This being simply because those underlying frameworks were not constructed ‘with a mindset’ that would support such behaviour. None- the-less, I stand by my proposal for consideration at TPAC, since it might be the case that my ‘use case’ has not been considered, and it might be the case that individuals attending can see a route to a solution… even if such a solution may be a long time coming and require a new version of CSS / XSL:FO (or require that TTML reference a different, equivalent but more flexible rendering framework). I note with interest that CSS3 includes flex-box layout functionality – cursory inspection would suggest this might be relevant.

Subject: New Features and CSS Compatibility

For anyone suggesting a new feature in TTML, e.g., shrink text to fit region, it won't be of much benefit to do so if there isn't an existing CSS mapping, or at least not much benefit in the open web platform (native presentation processors can do what they want).

So before you consider proposing something that has no CSS mapping, think first about how to get it into CSS.
