Function build_layout_and_info 

pub fn build_layout_and_info(
    dom: &Rc<RefCell<TreeNode<HtmlNodeType>>>,
    resolved_styles: &ResolvedStyles,
    measurer: &dyn TextMeasurer<TextStyle>,
    parent_text_style: TextStyle,
    chain: ElementChain,
) -> (LayoutNode, InfoNode)

Builds a layout tree (LayoutNode) and a render info tree (InfoNode) from the DOM.

Overview

• Recursively traverses the HTML DOM
• Applies resolved CSS declarations
• Computes layout-related styles
• Collects render-time information (color, font size, text)

Style resolution order (low → high priority)

1. Inherited values from parent

   • text_style

2. Resolved CSS declarations

   • Overrides inherited values when specified

3. HTML defaults / semantics

   • display (block, inline, etc.)
   • Text measurement for text nodes

Inherited properties

Only the following properties are inherited explicitly:

• text_style

All other style fields are initialized per node and are not inherited.

Parameters

• parent_text_style

These values must be passed from the computed result of the parent when calling this function recursively.

Returns

A tuple of:

• LayoutNode: used by the layout engine
• InfoNode: used for rendering (text, color, font size)
