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
  • Adobe Illustrator CS4 Hanging Punctuation
• Glyph scaling min/max/desired (for improving justification)
• text-emphasis-skip
• 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 CSS3 Module Text WD 20010517
• www-style: Vertical rhythm and images
  • http://stackoverflow.com/questions/4986944
  • http://webtypography.net/Rhythm_and_Proportion/Vertical_Motion/2.2.2/
• Implementations
  • -ms-layout-grid

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; }

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