Actually, there's not so much we can improve right now, in the sense that: * We need the ::-moz-page-content pseudo-element to be able to set `display` on the page, since that's a style rule rather than a @page rule. We could get away without it. * Keeping the current code-path (slightly cleaned up) is less code, for now at least. We can have a separate code-path or what not that actually performs the @page rule selector-matching and what not if needed when we get to named pages or other page selectors. Selectors like :first should be pretty trivial to implement, actually. We make some paged mode anon boxes non-inheriting anon boxes. This allows us to share the styles and is generally nicer. They don't need to inherit from anywhere. We could remove the origin handling and don't look at UA rules or what not, but it seems pretty harmless to do that. We also fix the name of the pseudo-elements to match the capitalization. Differential Revision: https://phabricator.services.mozilla.com/D104772

/* atom list for CSS anonymous boxes */
|
|
|
|
/*
|
|
* This file contains the list of nsAtoms and their values for CSS
|
|
* pseudo-element-ish things used internally for anonymous boxes. It is
|
|
* designed to be used as inline input to nsCSSAnonBoxes.cpp *only* through the
|
|
* magic of C preprocessing. All entries must be enclosed in the macros
|
|
* CSS_ANON_BOX, CSS_WRAPPER_ANON_BOX, or CSS_NON_INHERITING_ANON_BOX which will
|
|
* have cruel and unusual things done to it. The entries should be kept in some
|
|
* sort of logical order.
|
|
*
|
|
* The first argument to
|
|
* CSS_ANON_BOX/CSS_WRAPPER_ANON_BOX/CSS_NON_INHERITING_ANON_BOX is the C++
|
|
* identifier of the atom.
|
|
*
|
|
* The second argument is the string value of the atom.
|
|
*
|
|
* CSS_NON_INHERITING_ANON_BOX is used for anon boxes that never inherit style
|
|
* from anything. This means all their property values are the initial values
|
|
* of those properties. These ones must come first! Code relies on this.
|
|
* If this macro is not defined, it will default to CSS_ANON_BOX.
|
|
*
|
|
* CSS_WRAPPER_ANON_BOX is used for anon boxes that are used as wrappers around
|
|
* other frames during frametree fixup (e.g. table anonymous boxes, ruby
|
|
* anonymous boxes, anonymous flex item blocks, etc). These are also inheriting
|
|
* anon boxes, just like CSS_ANON_BOX. If this macro is not defined, it will
|
|
* default to CSS_ANON_BOX.
