Improve Mobile Responsiveness for Reusable Header and Sidebar

[jordan-ae]

Description:
Currently, the reusable header and sidebar components do not fully adapt to mobile devices, leading to a suboptimal user experience on smaller screens. This issue aims to enhance the mobile responsiveness of these components to ensure they are user-friendly and functional across all devices.

Acceptance Criteria:

1. Header Component:

   • The header should collapse into a hamburger menu on screens smaller than 768px.
   • Menu items should be accessible via a dropdown or slide-in menu when the hamburger icon is clicked.
   • The logo and any search bar should resize appropriately to fit smaller screens.
   • Ensure that touch targets are at least 48x48 pixels for better usability.

2. Sidebar Component:

   • The sidebar should be hidden by default on screens smaller than 768px and accessible via a toggle button.
   • When the sidebar is toggled open, it should slide in from the side and overlay the main content.
   • The sidebar should close when a user clicks outside of it or selects an item.
   • Ensure that all sidebar links and buttons are easily tappable on mobile devices.

3. General Responsiveness:

   • Both components should be tested on various screen sizes (320px, 375px, 414px, etc.) and on different devices (iOS, Android).
   • Ensure that the components are usable in both portrait and landscape orientations.
   • The transition animations should be smooth and not cause any performance issues on mobile devices.

Additional Requirements:

• Use CSS media queries and flexible layouts (e.g., Flexbox or Grid) to achieve responsiveness.
• Consider using a mobile-first approach to ensure the components are optimized for smaller screens by default.
• Ensure that the components are accessible, following WCAG guidelines, including proper ARIA attributes for screen readers.

Technical Considerations:

• Ensure that the changes do not break existing functionality on desktop or other screen sizes.
• Consider using CSS transitions or JavaScript for smooth animations.
• Test the components in different browsers (Chrome, Firefox, Safari, Edge) to ensure cross-browser compatibility.
