Is it ok to use flexbox everywhere? Will the download speed be affected?

Question

Flexbox

Is it ok to use flexbox everywhere? I heard that this increases the page load time, since the css properties of flexbox are processed by the browser for a long time.

Answer 1

Flexbox layout isn't slow https://developers.google.com/web/updates/2013/10/...

Answer 2

I’ve been using it constantly for 3 years now, I didn’t notice that it somehow affected the speed. Now I use grid + flex, the same thing, everything is fine quickly displayed.
