There have also been a few comments on “fixed spatial layout”.
Content can be resized to 400% without loss of content or functionality, and in a way that does not require the user to scroll to read a line of text, with the exception of any part of the content where a particular presentation is essential to the information being conveyed.

This takes the “particular presentation” from 1.4.5 rather than saying “fixed spatial layout”.  Just a thought to help eliminate a new phrase…

Thanks,

Longer, but addresses the scrolling concern:
Content can be resized to 400% without loss of content or functionality, and in a way that does not require the user to either scroll horizontally to read a line of horizontal text or to scroll vertically to read a line of vertical text, with the exception of any part of the content where fixed spatial layout is essential to the information being conveyed.

I think that we can support this one in Understanding and save the extra text:

Content can be resized to 400% without loss of content or functionality, and in a way that does not require the user to scroll to read a line of text, with the exception of any part of the content where fixed spatial layout is essential to the information being conveyed.

I think that the concept is simple enough that we should be able to write the SC without referring to the CSS definition for inline base direction, which I agree with Gregg will make the SC harder to read.

ok as long as you define a line of text.   Else I might look at a line of word wrapped text — and think you mean the whole line including the wrapped part — which indeed might require scrolling if the line is long enough and the screen small.

not sure how to clear up that ambiguity but other wiser seems to work.   maybe just add single?

Content can be resized to 400% without loss of content or functionality, and in a way that does not require the user to scroll to read a single line of text, with the exception of any part of the content where fixed spatial layout is essential to the information being conveyed.

Cribbing from 1.4.8, I think that we can keep it simple and say "in a way that does not require the user to scroll to read a line of text"

How about:
