[Bhavik0101]

Description

PThis PR fixes the unresponsive and inconsistent navigation header across the entire website. The previous implementation had conflicting CSS and missing JavaScript on different pages, leading to several UI bugs on mobile and tablet viewports..

Type of change

• [✅] Bug fix

• [ ✅] Improvement

How Has This Been Tested?

1.)Desktop View: Loaded the pages on a wide screen to ensure the desktop navigation bar looks and works correctly.

2.)Responsiveness Test: Resized the browser window from wide to narrow. Confirmed that the navigation links correctly collapse into a hamburger menu at the 1100px breakpoint, fixing the text overlap issue.

3.)Mobile Menu Functionality:

-On mobile view, clicked the hamburger icon to open the menu. Confirmed all links are visible and styled correctly.

-Navigated between pages using the mobile menu links. The header remains consistent and functional on every page.
