AH FormatterAH Formatter CSS Conformance

The following shows the current CSS specifications. ([CSS3-GCPM] etc. written at the beginning is an abbreviated name when refering to the specification.)

CAUTION: These specifications are not yet endorsed as W3C Recommendation. Especially CSS3 still has many drafts and there may be specification changes in the future. AH Formatter will continue to correspond to these specification changes.
  • [yes] in the list means that the formatting object or property is implemented.
  • [partial] means that the formatting object or property is partially implemented.
  • [no] means not implemented.

Sometimes items with [yes] have some limitation(s) that do not affect their ability to accomplish the specified tasks. With CSS3, a draft specification before the candidate, when a certain implementation is performed, it is considered as [yes]. This is because specification is not being fixed, we cannot judge whether it's partial or not clearly. See also CSS Reference.
