| 6 | # Global Layers |
| 7 | |
| 8 | Create components that persist across slides. |
| 9 | |
| 10 | ## Layer Files |
| 11 | |
| 12 | Create in project root: |
| 13 | - `global-top.vue` - Above all slides (single instance) |
| 14 | - `global-bottom.vue` - Below all slides (single instance) |
| 15 | - `slide-top.vue` - Above each slide (per-slide instance) |
| 16 | - `slide-bottom.vue` - Below each slide (per-slide instance) |
| 17 | - `custom-nav-controls.vue` - Custom navigation controls |
| 18 | |
| 19 | ## Z-Order (top to bottom) |
| 20 | |
| 21 | 1. NavControls / custom-nav-controls.vue |
| 22 | 2. global-top.vue |
| 23 | 3. slide-top.vue |
| 24 | 4. Slide Content |
| 25 | 5. slide-bottom.vue |
| 26 | 6. global-bottom.vue |
| 27 | |
| 28 | ## Example: Footer |
| 29 | |
| 30 | ```html |
| 31 | <!-- global-bottom.vue --> |
| 32 | <template> |
| 33 | <footer class="absolute bottom-0 left-0 right-0 p-2">Your Name</footer> |
| 34 | </template> |
| 35 | ``` |
| 36 | |
| 37 | ## Conditional Rendering |
| 38 | |
| 39 | ```html |
| 40 | <!-- Hide on cover layout --> |
| 41 | <template> |
| 42 | <footer v-if="$nav.currentLayout !== 'cover'" class="absolute bottom-0 p-2"> |
| 43 | {{ $nav.currentPage }} / {{ $nav.total }} |
| 44 | </footer> |
| 45 | </template> |
| 46 | ``` |
| 47 | |
| 48 | ## Export Note |
| 49 | |
| 50 | Use `--per-slide` export option when global layers depend on navigation state. |
