That <div class="marquee-box"> with `animation: scroll-left 18s linear infinite;` is just plain disrespect to the still working <marquee> element.

Yes it may still be working, but it’s deprecated! The marquee is dead, long live the marquee!

Upon inspecting with developer tools, I was pleased to find that <marquee> supports GPU acceleration. I vaguely recall reading lore of someone refactoring it up to modern standards in chromium a few years back.
