Make Navbar Sticky for Easier Top Navigation

Description
Currently, when scrolling down the About page, the navigation bar is not always accessible, making it hard to quickly return to the top or switch sections.
Improving the navbar to remain fixed (“sticky”) at the top of the page during scrolling will allow users to access navigation options at any time and easily return to the top with a single click.

Proposed Solution
Implement a sticky/fixed navbar that stays visible at the top of the page while scrolling.

Allow users to return to the top of the page by clicking the website logo or add a clear “Back to Top” option in the navbar.

Why This Matters
A sticky navbar significantly improves navigation and user experience, making it easy for users to explore the site or return to the top at any point.
