CSS Pseudo-Elements Module Level 4

  • 2016-06-08: ACTION-2059 Fred to review.
  • 2016-06-09: Fred Esch (talk) 13:45, 9 June 2016 (UTC) -- CSS Psuedo-Elements Module Level 4 has accessibility issues that we want to keep track of and work with the CSS WG on. Some areas of concern:
    • Highlight pseudo elements
      • Visual changes may not be relayed to AT because of security concerns (Section 3.6)
      • Low vision and color blind users might not detect
      • We may want to have a note added making authors aware of potential accessibility concerns
    • UA/AT handling of ::before, ::after and ::placeholder are of interest
      • Images used by ::before and ::after cannot be resized
    • Additions to CSS object model (Section 6) may conflict with ARIA rules for inclusion in accessibility tree (ie Pseudo-elements should be reachable by script, stylable from script, and available as event targets.)
    • Some of these issues could be addressed in a CSS AAM
    • Further detail on mailing list
  • 2016-06-15: APA discussion 15 June 2016. Will be something to address in CSS-AAM. Also Janina will write up a proposed comment.
