Add Dark Mode/Light Mode Toggle Feature

[Poushmita]

Description:

The Dark Mode button is not working. Currently, the website lacks a Dark mode/Light mode toggle, which would enhance user experience by allowing users to switch between dark and light themes as per their preference. I propose implementing a toggle button that enables users to easily switch between the two modes.

Features:

• Toggle Button: Add a button in the navigation bar or settings menu to switch between Dark and Light modes.
• Theme Persistence: Save the user’s theme preference using local storage, so it remains consistent across
• sessions.
• Smooth Transitions: Ensure smooth CSS transitions when switching themes.
• Accessibility: Make sure both modes are visually accessible, with appropriate colour contrasts.

Benefits:

1. Improved user experience with theme customization.
2. Reduced eye strain during night-time browsing.
3. More modern and engaging UI design.

Tech Stack:

HTML, CSS, JavaScript
