Adding Interactions slows down the site

Design help Animations & Interactions
1

Hey guys,

I am trying to implement interactions on page load on my site, but it slows down my site to the point where my interactions are not being played, but simply they are shown one by one on the page. I tried simplifying the interaction but it always happens the same.

For better understanding, what I am trying to do is to make the blue squares show one by one and then make the whole grey grid show at once.

Maybe it has something to do with the way I implemented things i.e. I should have created the grid in a different way? :thinking:

Anyways, you can find my public share link below.

Thanks for your help!
