22. “HTML documents should work well across different
browsers and platforms. Achieving interoperability lowers
costs to content providers since they must develop only
one version of a document. If the effort is not made,
there is much greater risk that the Web will devolve into
a proprietary world of incompatible formats”

23. “JavaScript is a high-level, dynamic, untyped, and

and CSS, it is one of the three core technologies of
World Wide Web content production”
