Hi Alastair and all, Yes. It certainly seems the discussion is going in circles. I proposed we go with the following with no note: SC Short name: Adapting text SC Text: 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. Can anyone not live with that?
