/**
|
||
|
|
* Enum defining the mode in which a sheet is to be parsed. This is
|
||
|
|
* usually, but not always, the same as the cascade level at which the
|
||
|
|
* sheet will apply (see nsStyleSet.h). Most of the Loader APIs only
|
||
|
|
* support loading of author sheets.
|
||
|
|
*
|
||
|
|
* Author sheets are the normal case: styles embedded in or linked
|
||
|
|
* from HTML pages. They are also the most restricted.
|
||
|
|
*
|
||
|
|
* User sheets can do anything author sheets can do, and also get
|
||
|
|
* access to a few CSS extensions that are not yet suitable for
|
||
|
|
* exposure on the public Web, but are very useful for expressing
|
||
|
|
* user style overrides, such as @-moz-document rules.
|
||
|
|
*
|
||
|
|
* Agent sheets have access to all author- and user-sheet features
|
||
|
|
* plus more extensions that are necessary for internal use but,
|
||
|
|
* again, not yet suitable for exposure on the public Web. Some of
|
||
|
|
* these are outright unsafe to expose; in particular, incorrect
|
||
|
|
* styling of anonymous box pseudo-elements can violate layout
|
||
|
|
* invariants.
