Task 1.4: Body Overflow Verification
Verification Time:
Verification Instructions
This page can be used to verify that the application does not manipulate document.body.style.overflow during initialization.
Manual Verification Steps
- Start the development server:
npm run dev
- Open the browser DevTools (F12)
- Go to the Console tab
- Before navigating to the app, run this code:
// Monitor body overflow changes
const originalOverflow = document.body.style.overflow;
console.log('Initial body overflow:', originalOverflow || '(not set)');
// Set up a MutationObserver to watch for style changes
const observer = new MutationObserver((mutations) => {
mutations.forEach((mutation) => {
if (mutation.type === 'attributes' && mutation.attributeName === 'style') {
const currentOverflow = document.body.style.overflow;
if (currentOverflow !== originalOverflow) {
console.error('❌ FAIL: Body overflow was changed to:', currentOverflow);
}
}
});
});
observer.observe(document.body, {
attributes: true,
attributeFilter: ['style']
});
console.log('✅ Monitoring body overflow changes...');
- Navigate to
http://localhost:3000
- Check the console for any error messages
- Verify the body overflow value:
// Check current body overflow value
console.log('Current body overflow:', document.body.style.overflow || '(not set)');
// Expected result: '' (empty string) or '(not set)'
// Should NOT be 'hidden'
