Intro section with dropdown navigation (HTML, CSS, & JS)

This was a challenging challenge for sure.

1. The drop down menu's and the side menu's definitely took the most time for me. Getting things arranged on big screens and small screens definitely was challenging. This challenge definitely tests your architectural skills when it comes to developing a page.

2. I am unsure about the tools and the way I have done challenge. Using Sass, Less or React Js could have made the development faster and more organized.

3. All feed back is welcome. Please do let me if I should have done things differently. Looking for a more efficient way to do this challenge. Thanks before hand.
