The primary issue here seems to be line length, which by default spans 100% of the viewport. I guess Simo is arguing for some clamping of HTML/BODY width which would result in a default line length that is more comfortable/acceptable. This relates to point 2 of WCAG 2.0 1.4.8 Visual Presentation (Level AAA) http://www.w3.org/TR/2008/REC-WCAG20-20081211/#visual-audio-contrast-visual-presentation "For the visual presentation of blocks of text, a mechanism is available to achieve the following: (Level AAA) 1. Foreground and background colors can be selected by the user. 2. Width is no more than 80 characters or glyphs (40 if CJK). 3. Text is not justified (aligned to both the left and the right margins). 4. 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. 5. Text can be resized without assistive technology up to 200 percent in a way that does not require the user to scroll horizontally to read a line of text on a full-screen window." A very naive bit of CSS in the browser default stylesheet, along the lines of html { max-width: 70em; } or similar would do the trick...however, this would break compatibility with pretty much all current and legacy web content out there...so I'd say it's unlikely to be implemented. At best, browsers could be made to include a special "reader" mode perhaps that forces this, but users would have to explicitly turn it on/off. P -- Patrick H.
