Navigation bar - structure

[ilFratus]

As a user,
when I'm on riplive.it website,
I should see a white navigation bar on the bottom of the page with 3 buttons:

• The player button (see: Navigation bar - live button #27)
• The mission button (see: Navigation bar - mission button #25)
• The hamburger button (see: Navigation bar - hamburger button #26)

and a link with the riplive.it logo to the website homepage (see: #28).

The navigation bar is always sticky to the bottom while I scroll the website content.
