Problem:

I’m having trouble with my React Navbar component. When I decrease the screen width, the mobile nav menu opens up, but the #242424 background doesn’t cover the entire width of the page. I’m not sure what I’m missing.

My Code:

Navbar.js:

import React, { useState, useEffect } from 'react';
import { Link } from 'react-router-dom';
import './Navbar.css';
import { Button } from './Button.js';

function Navbar() {
    const [click, setClick] = useState(false);
    const [button, setButton] = useState(true);
    
    const handleClick = () => setClick(!click);
    const closeMobileMenu = () => setClick(false);

    const showButton = () => {
        if (window.innerWidth <= 850) {
            setButton(false);
        } else {
            setButton(true);
        }
    };

    useEffect(() => {
        showButton();
        window.addEventListener('resize', showButton);
        return () => window.removeEventListener('resize', showButton);
    }, []);

    return (
        <>
            <nav className="navbar">
                <div className="navbar-container">

App.js

import React from 'react';
import './App.css';
import { BrowserRouter as Router, Routes, Route } from 'react-router-dom';
import Navbar from './components/Navbar';

function App() {
  return (
    <>
      <Router>
        <Navbar />
        <Routes>
          <Route path='/' exact />
        </Routes>
      </Router>
    </>
  );
}

export default App;

What I’ve Tried:

I have tried changing the height of the .nav-menu.active as calc(100vh – 80px);

But then it gives this result:

Somehow, the button is sticking to the bottom.

If you want anything extra to understand, I will provide it immediately!
