Question

css

Hello
Tell me, please, what could be the problem of animation freezes on macos? On windows it works correctly, but on a poppy everything lags
Here is a link to the site (Animations of transition from page to page and between screens)

Answer 1

It immediately catches your eye that when you scroll, you animate the top property. When switching between pages in scripts, there are constant calls to the inner*/outer*/offset*/client* properties (everything is minified, not parsed), as well as changes in the values ​​of left, height, and possibly something else. This all causes multiple page layout rebuilds and performance issues. I recommend reading the article on the topic .
