`. Its body is a size container — lay out inside with `@md:` etc., not `sm:`.
### `
`
An M3 bottom sheet, bound like ``: modal by default (scrim, inert page, drag the handle down or press Escape to close), `standard` for one that is part of the page. Props: `title`, `height` (`90dvh`), `actions` slot.
### ``, ``
```blade
@foreach ($photos as $photo)
@endforeach
```
A row of items that change size between M3's keylines as it scrolls (native scroll snap; items are masked, content keeps its size). ``: `layout` (`multi-browse` default, `hero`, `uncontained`, `full-screen`), `item-width` (px or any CSS length; the large size multi-browse aims for, the fixed size uncontained keeps, the cap for hero; 186 by default), `height` (205px), `padding` (px at the ends, 0), `centered` (hero), `label` (the region's name, "Carousel" by default), `controls` (previous/next buttons: default fine pointers only, `true` always, `false` never). ``: slot is an `![]()
` (fills and crops) or an element sized `size-full`; `label` overlays a line of text. A focusable `region` of `slide` groups named "n of m"; arrow keys move one item while the row has focus, Home/End to the ends. Works after a Livewire morph, in RTL and under reduced motion. Give items a `wire:key` in a loop.
## Testing the design
```php
use NoNameWeb\LivewireMaterial\Testing\DesignGuard;
it('uses only what compiles', function () {
expect(DesignGuard::scan([resource_path('views'), resource_path('js'), app_path()])
->forbidColours(['tertiary']) // roles this application's rules leave out
->violations())->toBe([]);
});
```
It fails on maryUI tags, daisyUI classes, colours the theme does not declare, unknown symbol names and Blade directives written inside a component tag (where they do not compile), with `path:line` for each.
## Conventions
- Components are anonymous Blade components: `` without a prefix, or `` when `config('livewire-material.prefix')` is set.
- Write class names out whole. Tailwind cannot compile `'text-'.$tone` or `type-{{ $size }}`, and the design guard cannot read them.
- The showcase at `/material` (local only, `MATERIAL_SHOWCASE=true` to force it) renders every token and component.
## Livewire traps
- Blade directives do not compile inside a component tag's attributes: `` reaches the browser as literal text. On a component tag use `{{ }}` and `:prop` bindings, or put the Alpine on a plain element inside the slot.
- Never pass `hidden`, a display utility or a position (`absolute`, `relative`) to a component: it is merged beside the component's own and whichever Tailwind emits last wins. Wrap the component in an element that carries it. A variant that only hides (`max-sm:hidden`) is safe.
- `$attributes->wire('model')->value()` is `false`, not `null`, when there is no `wire:model`, and `filled(false)` is true. Normalise with `?: null`.
- End every statement in a multi-line Alpine attribute with `;`: an inline `@if … @endif` inside it swallows the newline after it.
