= CSS text-size-adjust =

This page is for tracking the development of a standard '<code>text-size-adjust</code>' property. There are three known vendor prefixed implementations of it: <code>[http://dbaron.org/log/20111126-font-inflation -moz-], [http://msdn.microsoft.com/en-us/library/ff462082%28v=vs.92%29.aspx#sectionToggle2 -ms-], [https://developer.apple.com/library/ios/#DOCUMENTATION/AppleApplications/Reference/SafariWebContent/AdjustingtheTextSize/AdjustingtheTextSize.html -webkit-]</code>.

Web developers are using at least 4 prefixed implementations in the wild, including <code>[https://www.google.com/search?q=site%3Agithub.com+%22-o-text-size-adjust%22 -o-text-size-adjust]</code> which Opera does not implement (as of 2012-088 per Florian of Opera on the CSSWG telcon that morning).

==== define percentage values ====
The definition of <percentage> is not particularly clear. 

* Need to figure out what iOS Safari actually *does* for percentages. 

A somewhat reasonable guess might be that it sets a maximum inflation level, but relative to what?  Is '0%' equivalent to 'none', or is '100%', or are they both different from 'none' in some way?  If it actually just specifies the inflation that would be pretty bad.

* Create some test cases to figure out what iOS is doing for %s and test them on an iOS device (iPhone / iPod touch / iTouch).
* write-up percentage details accordingly

=== should for LCWD ===
* resolve all issues in draft
* develop a few prefixed-implementation test-cases for each value type
* demonstrate interoperability of prefixed-implementation test-cases
