AH FormatterAH Formatter CSS Conformance

AH Formatter V6.2's CSS implementation is based on the following specifications:

Many of CSS3 specifications are still under the draft or the state before draft. Although the specifications above are linked to the latest version at the time when this document was written, AH Formatter V6.2 implementation is not necessarily based on them. Each property in this document includes the link to the specification that is the base of the implementation. ([CSS3-GCPM] etc. written at the beginning is an abbreviated name when refering to the specification.)

  • [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.
