Module cascade

The main cascading algorithm of the style system.

Structs

Cascade 🔒

Declaration 🔒

DeclarationIterator 🔒

Declarations 🔒

The set of property declarations from our rules.

PrioritaryDeclarationPosition 🔒

“Prioritary” properties are properties that other properties depend on in one way or another.

Enums

CascadeMode

Whether we’re cascading for visited or unvisited styles.

FirstLineReparenting

Whether we’re resolving a style with the purposes of reparenting for ::first-line.

Functions

apply_declarations

NOTE: This function expects the declaration with more priority to appear first.

cascade

Performs the CSS cascade, computing new styles for an element from its parent style.

cascade_rules 🔒

iter_declarations 🔒

tweak_when_ignoring_colors 🔒

Type Aliases

DeclarationIndex 🔒

We track the index only for prioritary properties. For other properties we can just iterate.

DeclarationsToApplyUnlessOverriden 🔒

For ignored colors mode, we sometimes want to do something equivalent to “revert-or-initial”, where we revert for a given origin, but then apply a given initial value if nothing in other origins did override it.
