Thanks for the PR, @MohamadSalman11! Good catch—multiple is indeed not a valid value. TBH, I'm not entirely sure if background-blend-mode does actually anything in this case, but let's keep it for now, just in case.

Hi @julien-deramond ,

I was also wondering if the background-blend-mode actually does anything, as I don’t see any changes. It might be useful in a specific scenario. If you find anything, I can gladly make a new commit to remove it. Thanks a lot!
