Meet Landing Page Challenge Hub with SCSS, Gulp and GSAP

For this challange I worked the first time with GSAP. Because I have a very long timeline, I was looking for a solution to not show the animation everytime the page gets loaded. My idea was to set a cookie which expires after one day after an user has visited the page. Within this day, the animation would not play again. This approach worked - but it has brought with it another obstacle. Now I had a flackering effect whenever the page was loading - beacause there were some miliseconds where I had to check if the cookie is setted or not. My solution now is, to set the opacity of the body per default to zero and show it when the page is ready to load. Although this solutions works, it feels more like a workaround.

Has anyone expirence or ideas about how this could be done better? Also all other hints and advices are highly welcome.

Thanks in advance!
