Create the Prizes section

[cszach]

Branch: feature/prizes-section

What have been done so far

I have uploaded the images of the prizes with transparent background in the img/prizes folder.

What we need to do

1. Create a Prizes section on the website, according to the marketing team's design.
2. Add a new item on the navigation bar that links to the section.

A list of prizes can be found here. We have more than 3 prizes, so we will have to implement a carousel/slideshow-type of feature (notice the arrow icons in the design).

Also, do an on-hover spotlight/zoom type of effect (I dare you use JS for this)!
