Background image with svg not working?

Hi all.

I’m trying to add a full cover background image with two different svg images (one top and one on bottom)

html{
           background-image: url(https://raw.githubusercontent.com/cmb347827/project.github.io/main/bg-pattern-top-desktop.svg) top left no-repeat, url(https://raw.githubusercontent.com/cmb347827/project.github.io/main/bg-pattern-bottom-desktop.svg) bottom right no-repeat;
        }

but it’s not working.
I found this stackoverflow post:

https://stackoverflow.com/questions/9185434/using-svg-as-background-image

but it didn’t help much.
Any tips?
Thanks

Neither of those image URLs works for me.
