RE: Icon fonts - semantic elements

In my opinion, SC 1.3.1 is already met by providing aria-label or CSS off-screen text that is near/as subtree of the icon/icon link and conveys the same meaning.   The potential violation would be under SC 4.1.2. for the missing role.  But given that aria-label exists as text and CSS off-screen text may exist as text I'm not so sure this will pass as text doesn't really need a role.  I'd like to bring this up to the larger group -- but I do have concerns about this.  For example, sometimes pseudo content is used to display content such as a disclosure triangle of a tree item.  This pseudo content may have an equivalent already in aria-expanded, etc. and the pseudo content may be on another item with an existing role like tree item.  In this case we can't simply add role img and the information is already communicated programmatically. So we need to consider all of the potential cases.

Hi  Alastair, Stephen, Jim, and all,

Good question, Alastair.  If we can't associate James' technique with
2 SCs we could write up slightly different variations of the techniques for 1.3.1 and 4.1.2.

Question: Last year I wrote some techniques for Icon Fonts and for Unicode Characters that never got accepted by the AGWG. Do we want to want to edit/adjust/pursue any of them as part of this? The following are what are in the Wiki:

Icon Font with an On-Screen Text Alternative https://www.w3.org/WAI/GL/wiki/Icon_Font_with_an_On-Screen_Text_Alternative


Using aria-hidden=true on an icon font that AT should ignore https://www.w3.org/WAI/GL/wiki/Using_aria-hidden%3Dtrue_on_an_icon_font_that_AT_should_ignore


Unicode Character with an On-Screen Text Alternative https://www.w3.org/WAI/GL/wiki/Unicode_Character_with_an_On-Screen_Text_Alternative


Using aria-hidden="true" on Unicode characters that AT should ignore https://www.w3.org/WAI/GL/wiki/Using_a_Decorative_Unicode_Character


If we don't want to pursue them, we could recycle parts of them for James' technique.

Thoughts?

Thanks.

Kindest regards,
Laura
