From what I gather, I don’t know that there’s a new norm in this regard yet, besides recognizing that gifs are increasingly old & clunky (despite being fun & amusing), and so I don’t know if mp4s or webms or something else might be better if wanting to keep a site lightweight while still having some animated elements.
Animated content? Or site navigation elements, overlays, etc?
If the later go with the image assets svg, png, gif, etc since there’s better support for masking, css animations and so on.
Ah, sorry, not trying to be obtuse, content. I thought by referring to gifs it might make that clear.
I figured but thought I’d cover the bases
