# Spec: Navigation (Layer 06)
|
|
|
|
File: `src/layers/06-navigation.css`
|
|
|
|
## Purpose
|
|
|
|
Navigation patterns that go beyond the basic `nav` landmark. Sidebar navigation, table of contents, dropdown menus, navigation state management.
|
|
|
|
## Scope
|
|
|
|
### In scope
|
|
- `nav[data-nav="sidebar"]` — sidebar navigation tree
|
|
- `aside[data-toc]` — in-page table of contents
|
|
- Dropdown menus within navigation
|
|
- Active/current page indicators (`aria-current`)
|
|
- Mobile navigation patterns
|
|
- Navigation collapse/expand behavior
|
|
|
|
### Out of scope
|
|
- The `body > nav` landmark itself (→ landmarks layer)
|
|
- Breadcrumbs (→ components layer)
|
|
|
|
## Constraints
|
|
|
|
- References only semantic aliases from `01-tokens.css`
|
|
- Navigation must be keyboard-accessible
|
|
- Active states use `aria-current`, not classes
|
