Support for prefers-reduced-transparency

[yifaneye]

There are several semi-transparent elements on the carousel. I wanted to support users with prefers reduced transparency setting turned on. However, the prefers-reduced-transparency media query https://developer.mozilla.org/en-US/docs/Web/CSS/@media/prefers-reduced-transparency is not yet available as of 2 May 2021.

Please comment below if you see that prefers-reduced-transparency media query is available or if you have some other methods.
