Why is it different to requiring vertical scrolling? But I am happy for that part of the argument to be overturned. My argument was a two-parter though. The 'strong argument' objection to the requirement is that it's *not possible to achieve* -- because there is no pixel-width that is given to aim at. A layout that resizes perfectly on a 800x600 screen is likely to break immediately on a PDA, for example, and there's nothing I can to about it. I think that this requirement not testable... unless they specify a pixel width; and it's too technology-dependent - advanced PDAs such as the iPhone have horizontal scrolling as an integral part of the interface. Do you (or anyone else on eowg) have a suggestion on how we can rephrase the rquirement so that it is meetable but still preserves the gist of 'increase to 200% without making it unreadable'? >> More critically, the need for horizontal scrolling depends on the >> pixel-width of the viewport, and this is *impossible for the designer >> to control*. A moderately long word (or a URL) on a PDA will easily >> fail this - and some languages have a lot of long words.
