Split html file into three different file and folder, restructure webpage

[bhaumikmistry]

Restructure the cod. Move style/css code to css folder and html to be in index.html file and js code to js folder.

• html change
• css change
• js change

at the end we should have

-docs/
   |-src/
   |-css/
      |-style.css
   |-js/
      |-dark-mode.js

We want to have as many people as possible contribute to open-connect-art and teach people how to contribute and take part in the Hacktoberfest

Take a look at the project README.md for more details.
