RE: Zoom content updates Pt2

What we actually want to prevent horizontal scrolling, is scrolling that does *not* follow the block flow.

So we could use something like:
“Content can be zoomed to an equivalent width of 320 CSS pixels without loss of content or functionality, and without requiring scrolling perpendicular to the block flow except for parts of the content which require two-dimensional layout for usage or meaning.”

However, that seems unnecessarily technical, is two-dimensional really that complex? I seem to remember that being covered in primary school (before age 11?). It is certainly well before qualification level exams (e.g. GCSEs, high school diploma).
[Jason] Consider a document composed of text in the Latin alphabet that fits easily into whatever viewport you wish to consider (e.g., it’s a single paragraph). Suppose it requires horizontal scrolling after enlargement. The scrolling is only one-dimensional (there’s no vertical scrolling required because it fits within the viewport), and thus it meets your one-dimensionality condition but it requires horizontal scrolling and thus shouldn’t meet the proposed SC.
