Summary

Add a Dark Mode/Dark Theme to allow users to switch between light and dark interfaces.

Motivation

Many users prefer a dark interface while coding or browsing at night.Dark mode reduces eye strain and improves the overall user experience.

Possible Solution

Implement a toggle button in the UI to switch between light and dark themes.
Use CSS variables to define colors for lighting and dark modes, and switch them dynamically using javaScript.

Additional Context

Similar dark modes implementations can be found in most code editors and modern websites.This feature can be optional and remembered using local storage so users keep their preference.
