Meziantou.FrameworkLayoutChild Class
A child of a layout API container (https://drafts.css-houdini.org/css-layout-api-1/#layoutchild): an in-flow box, before its layout. The layout callbacks get the children of the box, read their styles, ask for their intrinsic sizes and lay them out.

| StyleMap | Gets the computed values of the childInputProperties of the layout class for the child (https://drafts.css-houdini.org/css-layout-api-1/#dom-layoutchild-stylemap). |
StyleMap
LayoutApiObjects.csGets the computed values of the childInputProperties of the layout class for the child (https://drafts.css-houdini.org/css-layout-api-1/#dom-layoutchild-stylemap).
public StylePropertyMapReadOnly StyleMap { get; }Methods
| Name | Description |
|---|---|
| IntrinsicSizes() | Asks for the border-box min-content and max-content contributions of the child (https://drafts.css-houdini.org/css-layout-api-1/#dom-layoutchild-intrinsicsizes): the task is completed when the layout runs its work queue. |
| LayoutNextFragment(LayoutConstraintsOptions?, ChildBreakToken?) | Lays out the child with the given constraints (https://drafts.css-houdini.org/css-layout-api-1/#dom-layoutchild-layoutnextfragment): the task is completed with the fragment when the layout runs its work queue. |
IntrinsicSizes()
LayoutApiObjects.csAsks for the border-box min-content and max-content contributions of the child (https://drafts.css-houdini.org/css-layout-api-1/#dom-layoutchild-intrinsicsizes): the task is completed when the layout runs its work queue.
public Task<LayoutIntrinsicSizes> IntrinsicSizes()Returns
Task<LayoutIntrinsicSizes> A task that fails with an InvalidStateError DomException when the child does not belong to the layout that is running.

LayoutNextFragment(LayoutConstraintsOptions?, ChildBreakToken?)
LayoutApiObjects.csLays out the child with the given constraints (https://drafts.css-houdini.org/css-layout-api-1/#dom-layoutchild-layoutnextfragment): the task is completed with the fragment when the layout runs its work queue.
public Task<LayoutFragment> LayoutNextFragment(LayoutConstraintsOptions? constraints = null, ChildBreakToken? breakToken = null)Parameters
constraintsLayoutConstraintsOptions?- The constraints, in the writing mode of the layout API container.
breakTokenChildBreakToken?- The break token of the previous fragment of the child, or null for its first fragment.
Returns
Task<LayoutFragment> A task that fails with a DomException: an InvalidStateError when the child or the break token does not belong to the layout that is running, a NotSupportedError in the intrinsicSizes() callback, a DataCloneError when the data of the constraints cannot be cloned.
