Change the background of the ISKCON page

[sameekshaa19]

Changing the background/ home page of the iskcon page.

Add a more convincing picture of Lord Krishna which resembles peace and moksh to the viewers.
I also wish to update the upcoming events list in the footer section which still shows 2023

Reason for Change:

The existing colour theme for Iskcon is not apt and very dull. It isn't captivating enough for a user to access the website's other features.

Changes I wish to do:
Change the colour theme of the page to a shade of blue.
Give a promising and a serene background to the page.
Edit the dates and upcoming events list.
