CSS 2.1 corrects a few errors in CSS2 (the most important being a new definition
of the height/width of absolutely positioned elements, more influence for HTML’s
"style" attribute and a new calculation of the ’clip’ property), and adds a few highly
requested features which have already been widely implemented. But most of all
CSS 2.1 represents a "snapshot" of CSS usage: it consists of all CSS features that
are implemented interoperably at the date of publication of the Recommendation.

Candidate Recommendation Exit Criteria
For this specification to exit the CR stage, the following conditions must be met:
1. There must be at least two interoperable implementations for every feature. For
the purposes of this criterion, we define the following terms:
feature
A section or subsection of the specification.
interoperable
passing the respective test cases in the test suite, or, if the implementa-
tion is not a web browser, equivalent tests. Every relevant test in the test
suite should have an equivalent test created if such a UA is to be used to
