Intentionally reducing the (audience) scope of test suites to web-savvy people is not desirable if there are 16 thousands (and growing) tests. I believe 90% (or more) of all 9735 tests of the CSS 2.1 test suite can be taken by ordinary people without problems; the rest, 10%, are more complex, involve a special font to install or to use a user stylesheet. > and it would be a distortion of > established > terminology to adopt layman terms that, by definition, are imprecise. Even if we were to recommend and adopt the "box" term in the pass/fail conditions sentence of tests, we would quickly find that it's too "broad", too general and not specific, not very descriptive. I have recommended [1] [2] to avoid and to ban the "box" term in the pass/fail conditions sentence of tests and to use exclusively instead rectangle|square|stripe|bar|line|grid and also to use qualifiers when needed, when required by the test. In the absolute, "a large filled green rectangle" may still involve a bit of interpretation and subjectivity but it's definitely a better description - in the relativity - than speaking of "a box". The terms rectangle|square|stripe|bar|line|grid have been already used by Ian Hickson in several of his tests and, from a geometry point of view, rectangle, square, line and grid are clear, understandable and reliable terms we can use and that we learned in high school. Again, in my opinion, the pass/fail conditions sentence should just be a short, clear and relevant verbal description of the expected layout preceded with "Test passes if there [is|are] (...)".
