-# Week 4 Plan: Forms & Interactions
-**Date Started:** 2026-04-16 | **Branch:** `week-4-forms` | **Estimated Duration:** 6–8 hours
-
----
-
-## 🎯 Week 4 Objectives
-
-### 1. Form Component System
-Build a reusable form component library with accessibility and styling.
-
-#### Components to Create:
-- **Input Fields** (`.form-input`)
-  - Text input, email, password, number
-  - States: default, focus, invalid, disabled
-  - Placeholder and label styling
-  - Error message display
-  - Character count support (optional)
-
-- **Textareas** (`.form-textarea`)
-  - Resizable or fixed height
-  - Auto-expanding variant
-  - Character limit indicator
-  - Syntax highlighting placeholder (optional)
-
-- **Select Dropdowns** (`.form-select`)
-  - Native `<select>` styling
-  - Multi-select support
-  - Custom styled variant (Alpine.js powered)
-  - Accessible keyboard navigation
-
-- **Checkboxes & Radio Buttons** (`.form-checkbox`, `.form-radio`)
-  - Custom styled (not browser defaults)
-  - Grouped layouts (inline, stacked)
-  - Label association (proper `<label for="">`)
-  - Accessible keyboard navigation
-
-- **Form Groups** (`.form-group`)
-  - Label + input + error message layout
-  - Spacing consistency
-  - Validation state indicators
-  - Help text support
-
-#### Styling Requirements:
-- ✅ Dark mode support (all components)
-- ✅ Light mode support (all components)
-- ✅ Focus indicators (2px ring, visible)
-- ✅ Error states (red outline, error message)
-- ✅ Disabled states (opacity, cursor)
-- ✅ WCAG AA contrast verified
-- ✅ Touch targets ≥44px (mobile)
-- ✅ Consistent spacing (8px grid)
-

-
-### 2. Form Layouts & Patterns
-Implement common form patterns using the component library.
-
-#### Layouts:
-- **Single Column**
-  - Contact form (name, email, message)
-  - Newsletter signup (email, subscribe button)
-  - Search form (input, submit)
-
-- **Multi Column**
-  - Registration form (2–3 columns on desktop, 1 on mobile)
-  - Filter/search form (label + input grids)
-
-- **Inline Forms**
-  - Search bar (icon + input + button)
-  - Newsletter widget (email + button)
-
-#### Validation Patterns:
-- **Client-side** (Alpine.js)
-  - Required field checking
-  - Email format validation
-  - Password strength indicator
-  - Conditional field visibility (show/hide based on selection)
-
-- **Server-side Integration**
-  - PHP contact form endpoint (`contact.php`)
-  - Error message display
-  - Success/confirmation messaging
-  - CSRF token handling (if applicable)
-
-#### Form States:
-- Empty (pristine)
-- Focused (active field)
-- Filled (has value)
-- Invalid (validation error)
-- Submitting (loading spinner)
-- Submitted (success message)
-
----
-
-### 3. Modals & Overlays
-Build reusable modal components for alerts, confirmations, and content.
-
-#### Modal Variants:
-- **Alert Modal** (`.modal-alert`)
-  - Single action button (OK, Close)
-  - Message display
-  - Optional icon
-
-- **Confirmation Modal** (`.modal-confirm`)
-  - Two action buttons (Confirm, Cancel)
-  - Title + message
-  - Danger state (red button for destructive actions)
-
-- **Content Modal** (`.modal-content`)
-  - Close button (X)
-  - Title + body + footer
-  - Large, medium, small sizes
-  - Scrollable content
-
-#### Modal Features:
-- ✅ Backdrop (semi-transparent overlay)
-- ✅ Keyboard handling (Escape to close, Tab trap)
-- ✅ Focus management (focus inside modal, restore on close)
-- ✅ Animation (fade in/out, slide up)
-- ✅ Responsive (full-screen on mobile, centered on desktop)
-- ✅ WCAG compliant (role="dialog", aria-labelledby)
-
-#### Alpine.js Integration:
-- `x-data="{ open: false }"`
-- `@click.outside="open = false"` (close on background click)
-- `@keydown.escape="open = false"` (close on Escape)
-- Smooth transitions with `x-transition`
-

-
-### 4. Interactive Patterns
-Enhance user interactions with feedback and validation.
-
-#### Patterns:
-- **Form Submission Feedback**
-  - Loading spinner during submission
-  - Success toast/notification
-  - Error notification with retry
-  - Progress indicator (for long forms)
-
-- **Inline Validation**
-  - Real-time feedback as user types
-  - Email format validation
-  - Password strength meter
-  - Character count display
-
-- **Loading States**
-  - Spinner component (animated SVG or CSS)
-  - Button disabled state during submission
-  - Loading overlay (for full-page actions)
-
-- **Toast Notifications**
-  - Success (green)
-  - Error (red)
-  - Info (blue)
-  - Warning (amber)
-  - Auto-dismiss (5 seconds)
-  - Manual close button
-
-- **Tooltips**
-  - Hover to show/hide
-  - Fixed positioning (stays visible)
-  - Arrow pointing to target
-  - Dark/light mode support
-
