CSS Selectors support in Opera Presto 2.2

There are three levels of CSS, CSS level 1, 2, and 3. CSS level 2 has a revision under development, referred to as "CSS level 2, revision 1" or "CSS 2.1" for short. CSS level 3 modules are in different stages of development; for example the Selectors module is in Last Call.

When level is set to "CSS 1/2" ("CSS 1/2.1"), the property was introduced with CSS Level 1, and extended with CSS Level 2 (revision 1).

See these Web pages for further reference.
