Loading.gif for 4k type monitor?

Question

css

Question on the picture loading.gif, perhaps strange, but still.
If we prepare ordinary jpg images in two sizes, for a regular monitor and for 4k separately twice as much.
Is it necessary to prepare two different loading.gifs?
The question is critical, because the gif itself is included in the current project in the design of the page. And size matters.

Answer 1

Your gif will get cached and "freeze" when you refresh the page again if you don't take care of it. And to load it again and again - well, nafik. Make a CSS preloader and don't invent problems for yourself.

Answer 2

There are a few points here.
- On css, I definitely won’t do such a thing myself. And the developer is unlikely to want to be confused like that.
- Custom GIF.
- I did not understand about the freeze. Why will she hang then?
I found a topic here to make loading in SVG format. In theory, this is a solution to the problem. I don’t know how correct, usable and cross-platform it is!?
