Website For My Game

My task was to look at web animations, i went onto the mafia 3 website as the game came out just recently to check out if they have some interesting animations/designs on their website. It wasn't anything special but they had something unlike other big name game websites.

I want my website to be the following: when someone goes on the link to it, the first thing they see will be a parallax effect (http://www.franckmaurin.com/blog/the-parallax-effect-with-jquery/) then you will scroll down and see what platforms my game will be available on and also the price, then there will be a trailer for my game below the available platforms. Furthermore a short writing about what My game is about and a couple of screenshots of it below the writing. Something really similar to this website: http://www.firewatchgame.com/
bellow i will show how i imagine my page

as you can see here is my loading screen which i wanted for my website. I done loads of research and was able to find a few of  those but this one caught my interest the most. Its a bit boring for now but as i get better at using html and css i will be able to make it better.
