Module layout 

Final data structures that represent the high-level UI layout

Structs

AxisStaticAlign

The alignment to apply to an out-of-flow box’s margin box within its static-position area in a single axis.

AxisStaticPosition

The static position of an out-of-flow box in a single axis: the alignment container (start/end coordinates) plus the alignment to apply to the box’s margin box within it.

Baselines

The first and last baselines of a node in the horizontal axis (i.e. baselines for horizontal text, measured as an offset from the top edge of the node’s border box).

CollapsibleMarginSet

A set of margins that are available for collapsing with for block layout’s margin collapsing

Layout

The final result of a layout algorithm for a single node.

LayoutInput

A struct containing the inputs constraints/hints for laying out a node, which are passed in by the parent

LayoutOutput

A struct containing the result of laying a single node, which is returned up to the parent node

OofCandidate

A record of an out-of-flow (position: absolute or position: fixed) box which has not yet been laid out because its containing block is an ancestor of its parent.

OofCandidates

A list of OofCandidates.

OofPositioningArea

The area of a container against which the insets of its out-of-flow (absolute/fixed) boxes are resolved: the container’s border box minus its borders and scrollbar gutters.

Enums

AxisStaticEdge

The physical alignment of an out-of-flow box’s margin box within its static-position area (per-axis).

DetailedLayoutInfo

The additional information from layout algorithm

RequestedAxis

An axis that layout algorithms can be requested to compute a size for

RunMode

Whether we are performing a full layout, or we merely need to size the node

SizingMode

Whether styles should be taken into account when computing size
