[FEATURE] Adding responsiveness in about page

[Radhika2255]

Is your feature request related to a problem? Please describe.
Yes. The current About page styling looks plain and lacks responsiveness, making it harder for users to read on smaller screens.

Describe the solution you'd like
I would like to improve the CSS of about.css by:
Adding proper spacing and padding.
Using a modern font with better readability.
Making the section responsive for both desktop and mobile.
Enhancing color contrast for accessibility.

Describe alternatives you've considered
Keeping the current styling (not preferred).
Using an external CSS framework like Bootstrap/Tailwind instead of custom CSS.
Applying inline styles directly in React components (but this reduces reusability).
