+3. Accessibility improvements (WCAG 2.1)
+
+### Implementation Details
+
+- Added form validation with error handling
+- Added ARIA attributes for accessibility
+- Created comprehensive test suite covering:
+  - Authentication flow
+  - Form validation
+  - Accessibility compliance
+  - Session management
+  - Error handling
+- Fixed responsive design issues:
+  - Added box-sizing: border-box for proper sizing
+  - Implemented responsive form container with margins
+  - Fixed input field overflow issues
+  - Ensured mobile-friendly layout

 ## Testing with Cypress
 
-This project uses Cypress for end-to-end testing. To run the tests:
+The project includes a comprehensive test suite covering authentication, security, and accessibility:
+
+### Running Tests
 
-1. Make sure the development server is running (`npm start`)
-2. In a new terminal, you can run Cypress in two ways:
+1. Start the development server:
 
-   ### Open Cypress Test Runner (Interactive Mode)
    ```bash
-   npm run cypress:open
+   npm start
    ```
-   This will open the Cypress Test Runner UI where you can:
-   - Choose your preferred browser
-   - See all test files
-   - Run tests interactively
-   - Watch tests run in real-time
 
-   ### Run Tests in Headless Mode
+2. Run tests in interactive mode:
+
    ```bash
-   npm run cypress:run
+   npm run cypress:open
    ```
-   This will run all tests in the terminal without opening the UI.
 
-   ### Run Tests with Dev Server
+3. Run tests in headless mode:
    ```bash
-   npm run test:e2e
+   npm run cypress:run
    ```
-   This command will:
-   1. Start the development server
-   2. Wait for it to be available
-   3. Run all Cypress tests
-   4. Shut down the server when done
+
+### Test Coverage
+
+The test suite includes:
+
+- Authentication flow validation
+  - Login form elements presence
+  - Input field behavior
+  - Successful login flow
+  - Invalid credentials handling
+  - Logout functionality
+- Security measures
+  - Session termination
+- Accessibility compliance
+  - ARIA attributes
+  - Required field indicators
+  - Error message announcements
+- Form validation
+  - Required fields
+  - Error state handling
