- Responsive Design
- Sidebar Layout Architecture
- Event Handling
- Dynamic UI Rendering
- Active Navigation State
- Mobile-first Design
Used Flexbox and media queries to adapt sidebar and header layout for different screen sizes.
JavaScript event listeners update content dynamically without page reload.
Active classes are added/removed programmatically on click.
Flexbox — because the layout is one-dimensional and requires flexible alignment.
