Add a Dark Theme to the Website

[diwakarshukla941]

I would like to suggest adding a dark theme feature to the website. Dark themes are popular as they reduce eye strain in low-light environments and enhance the user experience.

Proposed Solution:

Implement a toggle button to switch between light and dark modes.
Use CSS variables to manage colors and easily switch between themes.
Ensure that the dark theme is fully accessible (e.g., readable text, proper contrast).
Benefits:

Improved user experience in low-light conditions.
A modern, aesthetic addition to the website.
