CSS Conformance

Antenna House Formatter V7.4's CSS implementation is based on the following specifications:

Many of CSS3/CSS4 specifications are still under the draft or the state before draft. Although the specifications above are linked to the versions based on the Antenna House Formatter V7.4 implementation, Antenna House Formatter V7.4 does not implement them perfectly. 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 referring 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.
