Hi Alastair, Stephen, John, David, Lisa, Greg, and Everyone, Thank you Alastair! After reading Alastair's proposal for the paragraph bullet [1], does anyone think that it is not testable? Incorporating it into the SC we would have: <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 (2 lines). 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? Thanks everyone.
