====== Text Level 4 ======

===== Ideas =====

Ideas to consider for future CSS Text specs

  * Roman hanging punctuation
    * www-style: [[http://lists.w3.org/Archives/Public/www-style/2011Apr/0276.html]]
    * [[http://help.adobe.com/en_US/Illustrator/14.0/WS714a382cdf7d304e7e07d0100196cbc5f-63a5a.html|Adobe Illustrator CS4 Hanging Punctuation]]
  * Glyph scaling min/max/desired (for improving justification)
  * text-emphasis-skip
  * [[http://lists.w3.org/Archives/Public/www-style/2011May/0721.html|text-wrap:balance]] or something similar
  * Leading model control (placing leading above or below content area)

===== line-grid =====

  * Baseline Grid (define a grid for a block, and let line boxes either fall off the grid or snap to the next grid line) 
  * The original idea available in [[http://www.w3.org/TR/2001/WD-css3-text-20010517/#document-grid|CSS3 Module Text WD 20010517]]
  * www-style: [[http://lists.w3.org/Archives/Public/www-style/2011Feb/0468.html|Vertical rhythm and images]]

  * Implementations

===== text-spacing =====

  [ class-before class-after [ none | default [ [ [ min max ] | '/' alternate ] priority? ]? ] ]+

  @text-spacing-rule rule-name [ font-name [ ',' font-name ]* ] {
    line-head opening 0%;
    closing line-end 50%/0%;
    ideograph alphabet 25% 12.5% 50% 2;
  }

  - The relationshipo of expansion opportunities defined here and other properties (text-justify, word-spacing, letter-spacing) is an issue
  - JIS/JLREQ/InDesign style (trim and specify how much to add), or specify how much to add/remove?
    - Results differ if punctuation are proportional
  - Spaces are not consistent for: "]<big>[]</big>["
  - Can 'none' have optional min/max/alternate/priority? Does it allow expansion?
  - How to handle proportional punctuation is still an issue
  - '/' syntax is used only for closing+line-end, where CSS3 Text defines by the "if it fits" clause
