, , , , , , ,


 

1. تعارف

آئی ٹی درسگاہ سرٹیفائیڈ فرنٹ اینڈ ڈویلپر (ITDCFeD) پروگرام کے نویں ہفتے میں خوش آمدید۔ اس Week #9 میں modern web applications کے core UI patterns سیکھیں گے:

  • Modal Popups (Login, Course Enrollment)

  • Toast Notifications (temporary feedback)

  • Notification Center (persistent alerts)

  • Form Handling (validation + submission)

یہ patterns SaaS apps، e-commerce، admin dashboards میں industry standard ہیں۔

2. اس لیکچر / پروجیکٹ کے اہداف

Week #9 کے اختتام تک آپ:

  • CSS-Only Modal Animations (scale + backdrop blur)

  • Toast Messages (auto-dismiss + multiple types)

  • Notification Center (persistent + categorized)

  • Form Validation (required fields + submission)

  • Advanced Animations (cubic-bezier + staggered effects)

  • Z-Index Management (layering system)

3. Live Demo اور Source Code (CodePen)

🔗 Live Demo + Source Code (CodePen):
https://codepen.io/mmshahid73/pen/KwMZLEM

استعمال کا طریقہ:

  • Modal Buttons click → Login/Course Enroll popups

  • Toast Button → Temporary notification (4s auto-dismiss)

  • Notification Buttons → Persistent center + 4 types

  • Forms Submit → Success toast + modal close

  • Outside Click → Modal close (user-friendly)

  • Clear All → Notification center reset

4. پروجیکٹ کی ساخت – Step-by-Step وضاحت

4.1 HTML – Component Architecture

text
- Demo Buttons: 5 trigger buttons (Modal/Toast/Notification)
- 2 Modals: Login (simple) + Course Enroll (complex)
- Notification Center: Fixed right + slide-in animation
- Toast Container: Fixed bottom-right + stackable

4.2 CSS – Advanced UI Patterns

text
✅ Modal Animation: scale(0.7→1) + translateY + cubic-bezier bounce
✅ Toast Slide: translateX(400px→0) + elastic easing
✅ Notification Center: Right slide + max-height scroll
✅ Glassmorphism: backdrop-filter + rgba backgrounds
✅ Color-coded: Success(green), Error(red), Warning(yellow), Info(blue)
✅ Mobile: 90vw width + responsive positioning

4.3 JavaScript – Event-Driven Logic

text
1. openModal()/closeModal(): classList + setTimeout stagger
2. showToast(): Dynamic creation + 4s auto-remove
3. addNotification(): insertBefore (newest first) + timestamp
4. Form Handling: preventDefault() + success feedback
5. Outside Click: event.target vs modal-content detection
6. Global Event Listeners: Efficient delegation

5. Week #9 اسائنمنٹ / Homework

لازمی کام:

  1. CodePen Fork کریں: https://codepen.io/mmshahid73/pen/KwMZLEM
