Hi John, Greg, Lisa, and Everyone, After reading the "Adapting Text Units: Spaces, paragraphs, and ems" thread [1] and Stephen's latest rationale [2], can anyone not live with the following text: <Start SC Text> If the technologies being used allow the user agent to adapt style properties of text, then no loss of essential content or functionality occurs by adapting all of the following: 1. line height (line spacing) to at least 1.5 times the font size. 2. spacing underneath paragraphs to at least 2 times the font size. 3. letter spacing (tracking) to at least 0.12 times the font size. 4. word spacing to at least 0.16 times the font size. Note: Examples of text that are typically not affected by style properties are open captions and images of text, which are not expected to adapt. Editor's note: The Working Group seeks to include overriding text color, background color, and font-family as part of this SC, but is not yet able to identify a way to do so that is sufficiently testable. <End SC Text> Can anyone not live with that? Thank you all very much. Kindest Regards, Laura [1] https://lists.w3.org/Archives/Public/w3c-wai-gl/2017JulSep/thread.html#msg61 [2] https://lists.w3.org/Archives/Public/w3c-wai-gl/2017JulSep/0111.html On 7/13/17, Repsher, Stephen J <stephen.j.repsher@boeing.com> wrote: > Hi John, > > That’s actually incorrect with regard to letter and word spacing.
