# mobile-layout Specification
## Purpose
Provide responsive layout capabilities that detect user devices and adapt the UI for optimal mobile experience. This extends the existing "Responsive Layout and Navigation" requirement in frontend-core to include mobile devices (<768px).
## MODIFIED Requirements
### Requirement: Responsive Layout and Navigation
The frontend SHALL provide a responsive layout that works on desktop, tablet, and **mobile** devices with intuitive navigation. The system SHALL detect the device type and switch layouts accordingly.
#### Scenario: Mobile layout (<768px)
- **WHEN** viewed on mobile devices (<768px width)
- **THEN** the system SHALL:
- Display a simplified header with hamburger menu
- Show sidebars as full-screen slide-in panels (not inline)
- Display a bottom toolbar with frequently used actions
- Use single-column layout for content
- Ensure all touch targets are at least 44x44 pixels
#### Scenario: Tablet layout (768px-1024px)
- **WHEN** viewed on tablet (768px-1024px)
- **THEN** the system SHALL:
- Collapse sidebars to icons or overlay panels
- Use full width for content areas
- Stack panels vertically when needed
#### Scenario: Desktop layout (>1024px)
- **WHEN** viewed on desktop (>1024px)
- **THEN** the system SHALL:
- Display full navigation and sidebars inline
- Show room list and detail side-by-side when applicable
- Display member/file panels as sidebars
## ADDED Requirements
### Requirement: Device Detection
The frontend SHALL provide hooks for detecting device type based on viewport width.
#### Scenario: Detect mobile device
- **WHEN** the viewport width is less than 768px
- **THEN** `useIsMobile()` hook SHALL return `true`
- **AND** the UI SHALL render mobile-optimized components
#### Scenario: Detect tablet device
- **WHEN** the viewport width is between 768px and 1023px
- **THEN** `useIsTablet()` hook SHALL return `true`
#### Scenario: Detect desktop device
- **WHEN** the viewport width is 1024px or greater
- **THEN** `useIsDesktop()` hook SHALL return `true`
#### Scenario: Handle viewport resize
- **WHEN** the user resizes the browser window across breakpoints
- **THEN** the hooks SHALL update their return values
- **AND** the UI SHALL transition smoothly to the appropriate layout
### Requirement: Mobile Navigation
The frontend SHALL provide mobile-optimized navigation patterns for small screens.
#### Scenario: Display mobile header
- **WHEN** on mobile layout in room detail view
- **THEN** the system SHALL:
- Show room title (truncated if necessary)

#### Scenario: Display bottom toolbar
- **WHEN** on mobile layout in room detail view
- **THEN** the system SHALL:
- Show a fixed bottom toolbar above the message input
- Include buttons for: Files, Members
- Use icons with labels for clarity
- Ensure toolbar doesn't overlap with device safe areas
### Requirement: Mobile Sidebars
The frontend SHALL display sidebars as slide-in panels on mobile devices.

- **WHEN** user taps the Members button on mobile
- **THEN** the system SHALL:
- Slide in a full-screen panel from the right
- Display dark overlay behind the panel
- Show member list with larger touch targets
- Include a close button at the top of the panel
#### Scenario: Close sidebar panel
- **WHEN** user taps the close button or backdrop overlay

### Requirement: Touch-Friendly Interactions
