Module positioning 

Final positioning of layout nodes (relative, absolute, and fixed schemes)

Structs

StickyConstraints

Sticky positioning constraints computed at layout time. At scroll time, the sticky box’s position is clamped so that it remains within the sticky view rectangle (scrollport inset by these values).

Functions

adjust_relative_positions

Final pass to shift relatively positioned elements from their static flow position.

adjust_sticky_positions

Adjusts positions of sticky-positioned elements based on scroll offset.

find_absolute_containing_block_rect

Helper to find the containing block for an absolutely positioned element. CSS 2.1 Section 10.1: The containing block for absolutely positioned elements is the padding box of the nearest positioned ancestor.

get_position_type

Looks up the position property using the compact-cache-aware getter.

position_out_of_flow_elements

After the main layout pass, this function iterates through the tree and correctly calculates the final positions of out-of-flow elements (absolute, fixed).
