Redesigning of Nav-bar

## Description
The color theory of the nav bar is not that appealing even the hover effects on the nav elements are not making them look good.
**Describe the solution you'd like**
I want to enhance the nav bar because it is the first element of our website someone will look at, I want to align nav items and give them a different hover effect to make them look appealing.
**Describe alternatives you've considered**
I want to change the color theory of the nav bar for which I am considering a new color palate that will go with the website theme.
