Imagine this DOM:\[code\]<header> <h1> header </h1> <other elements/> <nav> nav </nav></header><div> content</div>\[/code\]Both header and nav are positioned as \[code\]fixed\[/code\].The content div is positioned as \[code\]relative\[/code\].I need to create a stack, with z-index, in this order (from top to bottom):
- header *:not(nav)
- content
- nav
