Adding Dark mode

[Priyanshi0112]

This will be helpful in :

• Reduced Eye Strain: Dark mode lowers the overall brightness, especially in low-light environments, reducing strain on the eyes. It is particularly helpful for users who spend extended periods browsing at night or in dimly lit conditions.

• Improved Battery Life: On devices with OLED or AMOLED screens, dark mode can significantly reduce power consumption. Dark pixels use less energy, which can help extend battery life for mobile and laptop users.

• Enhanced Accessibility: Some users with visual impairments or light sensitivities find dark mode more comfortable and easier to read. Providing this option makes the website more accessible to a wider audience.

• Modern and Aesthetic Appeal: Dark mode offers a sleek, modern look that many users prefer for its visual appeal. Websites with dark themes can stand out and align with popular user interface trends, attracting users who favor contemporary designs.

• User Personalization: Offering dark mode adds a level of customization to the user experience. It gives visitors the flexibility to choose between light and dark themes based on their preferences, fostering engagement and retention by enhancing the site's usability.

Adding dark mode provides both functional and aesthetic benefits, improving user comfort and overall experience on the website.
