CSS3 Text Decoration


   Topic: Text decoration issues

   <glazou> http://dev.w3.org/csswg/css-text-decor-3/issues-lc-2013#issue-6

   fantasai: first is from dbaron, about dropping

             text-underline-position: alphabetic

   <glazou> http://lists.w3.org/Archives/Public/www-style/2013Mar/0529.html

   fantasai: your issue is that alphabetic is requesting to use font data

             except when it's incorrect

   dbaron: My big problem with this is that I don't know how it would really

           be implemented

   fantasai: I'd like to hear from jdaggett.

   fantasai: He knows a lot about font metrics and what's an appropriate

             way to use them

   glazou: fantasai, can you take action to ping jdaggett

   fantasai: did ping, haven't heard back

   glazou: maybe handle off call?

   fantasai: does anyone else have feedback on issue? Esp. Adobe?

Sorry I could not make today's call; had a medical problem that intervened.

First, I do not yet understand what the problem to be solved is. The feedback that I received was the most fonts did have an underline position metric and that is what should be used. Which is exactly what is suggested in the current text.  So, for Adobe to have more input, we need to know what problem needs solving.

Also, it was noted that the example of an alphabetic underline on what appears to be Time Roman is show too low; that is, it is below the underline position in the Time Roman font.
