Module styling 

Styling system — powered by Mozilla’s Stylo CSS engine.

This is the ONLY module that imports Stylo types. All other code (dom, layout, paint, public API) uses re-exports from here.

Modules

builder

Type-safe style API — zero CSS parsing, direct PropertyDeclaration.

style_structs

Property struct groups — access computed values by category. Usage: computed_values.get_box().clone_display() The module where all the style structs are defined.

taffy_bridge

Stylo ↔ Taffy bridge — converts ComputedValues to Taffy layout styles.

units

CSS unit helpers — px(100.0), pct(50.0), em(1.5), etc.

values

Computed value types that exist as standalone re-exports.

Structs

AbsoluteColor

Stylo color type — used by bg(), border_color(), etc. An absolutely specified color, using either rgb(), rgba(), lab(), lch(), oklab(), oklch() or color().

Arc

Arc wrapper used by Stylo. An atomically reference counted shared pointer

ComputedValues

Computed style values for an element. All CSS properties accessible via property struct getters (e.g. cv.get_box().clone_display()). The struct that Servo uses to represent computed values.

PropertyDeclarationBlock

A parsed CSS declaration block (inline styles, stylesheet rules). Overridden declarations are skipped.

SharedRwLock

Stylo’s shared lock — needed to read locked declarations. A shared read/write lock that can protect multiple objects.

SharedRwLockReadGuard

Stylo’s shared lock — needed to read locked declarations. Proof that a shared lock was obtained for reading (servo).

Enums

BorderStyle

CSS border-style keyword — Solid, Dashed, Dotted, None, etc. A specified value for a single side of a border-style property.

Functions

initial_values_arc

Returns initial (default) computed values wrapped in Arc. Stylo equivalent of the old ComputedStyle::default(). Uses a static cache to avoid repeated allocation.
