Hello everyone, After yesterday's discussion [1], Andrew's proposed rewrite [2] and Jon's concerns with the rewrite [3] what do you think about rewriting the current adapting-text SC, which is: No loss of content or functionality on a webpage is caused by overriding: 1. font family to Verdana, or 2. foreground and background to white on black, or 3. line height of all text to 1.5, letter spacing to 0.12em, and word spacing to 0.16em. To read: Either a mechanism exists to adapt textual information or no loss of content or functionality exists when: * font family is overridden by the user. * foreground and background colors are overridden by the user. * line spacing (leading) is at least space-and-a-half within paragraphs, and paragraph spacing is at least 1.5 times larger than the line spacing. * letter spacing (tracking) is at least 0.12 em, and word spacing is at least 0.16 em. With this approach the offending hard coded metrics are removed and the understanding and technique documents will have to provide the details. Patrick and David this version incorporates Andrew's suggestion that authors need to create mechanisms (as a last resort)... and just about gets us back to where we started. Thoughts? Ideas for improvement? Is this getting closer to what people can live with? Please reply in the GitHub issue: https://github.com/w3c/wcag21/issues/78 Thank you.
