|
|
|
|
// A logical property group is one that defines the corresponding physical
|
|
// longhand properties that could be set by a given set of logical longhand
|
|
// properties. For example, the logical property group for margin-block-start
|
|
// (and the other three logical margin properties) is one that contains
|
|
// margin-top, margin-right, margin-bottom and margin-left.
|
|
//
|
|
// Logical property groups are defined below using one of the following
|
|
// macros, where the name_ argument must be capitalized LikeThis and
|
|
// must not collide with the name of a property's DOM method (its
|
|
// method_ in nsCSSPropList.h):
|
|
//
|
|
// CSS_PROP_LOGICAL_GROUP_SHORTHAND(name_)
|
|
// Defines a logical property group whose corresponding physical
|
|
// properties are those in a given shorthand. For example, the
|
|
// logical property group for margin-{block,inline}-{start,end}
|
|
// is defined by the margin shorthand. The name_ argument must
|
|
// be the method_ name of the shorthand (so Margin rather than
|
|
// margin).
|
|
//
|
|
// CSS_PROP_LOGICAL_GROUP_BOX(name_)
|
|
// Defines a logical property group whose corresponding physical
|
|
// properties are a set of four box properties which are not
|
|
// already represented by an existing shorthand property. For
|
|
// example, the logical property group for
|
|
// offset-{block,inline}-{start,end} contains the top, right,
|
|
// bottom and left physical properties, but there is no shorthand
|
|
// that sets those four properties. A table must be defined in
|
|
// nsCSSProps.cpp named g<name_>LogicalGroupTable containing the
|
|
// four physical properties in top/right/bottom/left order.
|
|
//
|
|
// CSS_PROP_LOGICAL_GROUP_AXIS(name_)
|
|
// Defines a logical property group whose corresponding physical
|
|
// properties are a set of two axis-related properties. For
|
|
// example, the logical property group for {block,inline}-size
|
|
// contains the width and height properties. A table must be
|
|
// defined in nCSSProps.cpp named g<name_>LogicalGroupTable
|
|
// containing the two physical properties in vertical/horizontal
|
|
// order, followed by an nsCSSProperty_UNKNOWN entry.
|
|
//
|
|
// CSS_PROP_LOGICAL_GROUP_SINGLE(name_)
|
|
// Defines a logical property group in which the logical property always
|
|
// maps to the same physical property. For such properties, the
|
|
// "logicalness" is in the value-mapping, not in the property-mapping. For
|
|
// example, the logical property "-webkit-box-orient" is always mapped to
|
|
// "flex-direction", but its values ("horizontal", "vertical") map to
|
|
// different flex-direction values ("row", "column") depending on the
|
|
// writing-mode. A table must be defined in nsCSSProps.cpp named
|
|
// g<name_>LogicalGroupTable containing the one physical property,
|
|
// followed by an nsCSSProperty_UNKNOWN entry.
