I'm trying to send a patch which makes the about-page look a bit better. When I try `--color-primary-900` it's only the dark theme. When I try `--bg-primary-900` it doesn't work since it's transparent I think.

I'm trying to apply a little shadow behind the about-page, i've modified the JSX/html of the about page to `about-page bg-white dark:bg-primary-900`, but that's for background only, i want to apply that to the box-shadow as well
