using dark mode in a nextjs web app with tailwind, when scrolling, if you scroll past the scroll container (almost like your bouncing off the bottom or top of the page when scrolling), the dark mode isn't extending all the way, so the color isn't applying and it's just the previous color underneath (white in this case), what is the reason for this and is there a way to extend the dark mode fully?

stackoverflow and tailwindcss.com in dark mode handle this well and the dark mode extends fully on the whole page
_app.tsx
<Store state={state} dispatch={dispatch}>
<Head>
<meta charSet="UTF-8" />
<meta
name="viewport"
content="width=device-width, initial-scale=1.0"
/>
</Head>
<div className="h-screen dark dark:bg-black dark:text-white overscroll-auto lg:overscroll-contain">
<Component {...pageProps} id="app" />
</div>
</Store>{" "}

You must apply the styles to the body or :root (HTML) element. For the examples, I'll show them applied to the :root element.
You have two primary options in Next.js - global stylesheet or inline.
Global stylesheet with tailwind directives
global.css
@tailwind base;
@layer base {
:root {
@apply dark:bg-black dark:text-white;
}
}
To apply styles inline, you must create a custom _document page. Again, you can apply the styles to either the body or html tags.
_document.js
import { Html, Head, Main, NextScript } from 'next/document'
export default function Document() {
return (
<Html className="dark:bg-black dark:text-white">
<Head />
<body>
<Main />
<NextScript />
</body>
</Html>
)
}
I was running into the same problem. Turns out it was because my dark background/foreground color styling was on a React component (a container layout component) rather than being on the body element.
I fixed it by setting the dark background/foreground directly on the body element in my css file:
@layer base {
body {
@apply dark:bg-slate-800 dark:text-white;
}
}
Then in your pages/_app.jsx file or wherever, you can call document.documentElement.classList.add("dark"); and the dark mode will be set properly even on scroll.
