Prevent div from extending beyond the screen in Next.js layout

I'm working with a Next.js project and have the following layout setup. My issue is that a div in my Page.tsx extends beyond the screen, causing unwanted overflow. I would like to make sure that the content is fully contained within the viewport.

Here are the relevant parts of my code:

Layout.tsx code

import type { Metadata } from "next";
import { Geist, Geist_Mono } from "next/font/google";
import "./globals.css";
import { SidebarProvider, SidebarTrigger } from "@/components/ui/sidebar";
import { AppSidebar } from "@/components/app-sidebar";
import { AuthProvider } from "@/AuthContext";
import { ThemeProvider } from "@/components/theme-provider"

const geistSans = Geist({
  variable: "--font-geist-sans",
  subsets: ["latin"],
});

const geistMono = Geist_Mono({
  variable: "--font-geist-mono",
  subsets: ["latin"],
});

export const metadata: Metadata = {
  title: "Lumos",
  description: "SNU CGPA Calculator",
};

export default function RootLayout({
  children,
}: Readonly<{
  children: React.ReactNode;
}>) {
  return (
    <html lang="en" suppressHydrationWarning>
      <body className={`${geistSans.variable} ${geistMono.variable} antialiased`}>
      <ThemeProvider
            attribute="class"
            defaultTheme="system"
            enableSystem
            disableTransitionOnChange
          >
        <SidebarProvider>
          <AuthProvider>
            <AppSidebar />
          </AuthProvider>
          <main>
            {children}
          </main>
        </SidebarProvider>
      </ThemeProvider>
      </body>
    </html>
  );
}

Page.tsx Code

import { ModeToggle } from "@/components/dark-mode-toggle";

export default function Home() {
  return (
      <>
        <div className=" border border-red-200 w-screen">
          <div className=" absolute right-0 m-4 outline outline-1 dark:outline-white outline-black rounded-sm">
            <ModeToggle />
          </div>
          <div className="flex items justify-center h-full w-full">
            Hello
          </div>
        </div>
      </>
  );
}

Current Output enter image description here

Issue: As you can see in the screenshot below, the content (div) extends beyond the screen, causing an unwanted horizontal scroll. I want to ensure that all content remains within the viewport without causing overflow.

What I've tried:

I used w-screen for width, but it didn't solve the issue. The h-full on the child div seems to make it extend beyond the screen as well.

Can anyone suggest how to fix the overflow issue? I would like to make sure the content stays within the bounds of the viewport.
Solution

  • it is because the w-screen in the Home div that wraps the full component instead you can do

    calc(w-screen - sidebarWidth)

    in tailwind will be like this

     <div className=" border border-red-200 w-[calc(100vw_-_sidebarWidth)]">
          <div className=" absolute right-0 m-4 outline outline-1 dark:outline-white outline-black rounded-sm">
            <ModeToggle />
          </div>
          <div className="flex items justify-center h-full w-full">
            Hello
          </div>
        </div>
