Make a single page Codeuino website

The Codeuino website can be accessed currently at http://codeuino.org and it has been divided into various sections like **Home**, **Activities**, **Teams**, **Docs**, **About Us**, **Blog**, **Code of Conduct** and **Join Us.**

**PURPOSE:** So the purpose of this issue is to make a single-page website instead of creating other web pages.
These are the following things to be restored/improved in existing website:

- Nav Bar should contain **About Us**, **Projects**, **Programs**, **Leadership**, **Docs**, **Collaborate**, **Code of Conduct**, **Blogs**, **Donate**
- About Us: This will not be a new page. On clicking on About Us section it will be hovered down on the area on the same page that contains "What is Codeuino?", "What we do?", "Who we are?"
- Projects: This will not be a new page. On clicking on Projects section it will be hovered down on the area on the same page containing the detail of the projects like showing currently. Presently website has 3 projects shown, please add 3rd project as well.
- Programs: This will not be a new page. On clicking on the Programs section it will be hovered down on the area on the same page that contains the information as shown below. You should mention in the same way about "Google Summer of Code", "Google Code-In", "Linux Foundation Mentorship Program", "Codeuino Internship Program"
- Leadership: This will be a new web page that will contain the heading "Leadership Board", "Leadership Team management" and "Contributors". This page can be made like this
- Docs: Docs will only contain the link to docs.codeuino.org
- Collaborate: This will not be a new page. On clicking on the Collaborate section it will be hovered down on the area on the same page that contains "Supporters", "Sponsors", etc. We can also show like this that how one can support us.

- Code of Conduct will be a direct link to doc page containing Code of Conduct
- Join Us: This will be on the same page with minor contexts giving brief about how one can join.

Also, Improve the footer section and try to make it responsive for mobile, Tablet and Laptop version
