litterally all i had to do was this (and a couple other things that didn't listen to it):

<style>
    @media (prefers-color-scheme: dark) {
        body {
            background-color: black;
            color: rgb(255, 255, 255);
        }
    }

    @media (prefers-color-scheme: light) {
        body {
            background-color: white;
            color: black;
        }
    }
</style>
