How to implement a sticky footer in a Next.js application

Implementing a sticky footer in a Next.js application involves using CSS to create a layout where the footer stays at the bottom of the page regardless of the content height. Here's a step-by-step guide on how you can achieve this:

1. Create a layout component: Start by creating a layout component that will wrap your entire application. This component will include the main content and the sticky footer.

   jsxCopy code
   // components/Layout.js
   import React from 'react';
   import styles from './Layout.module.css';
   
   const Layout = ({ children }) => {
     return (
       <div className={styles.wrapper}>
         <div className={styles.content}>{children}</div>
         <div className={styles.footer}>Your Sticky Footer Content</div>
       </div>
     );
   };
   
   export default Layout;
   

2. Create CSS modules for styling: Create CSS modules to style your layout component. Here, we'll define the styles for the wrapper, content, and footer.

   cssCopy code
   /* styles/Layout.module.css */
   .wrapper {
     display: flex;
     flex-direction: column;
     min-height: 100vh;
   }
   
   .content {
     flex: 1;
     padding: 20px;
   }
   
   .footer {
     flex-shrink: 0;
     padding: 20px;
     background-color: #333;
     color: #fff;
     text-align: center;
   }
   

3. Use the layout component in your pages: Now, use the Layout component in your Next.js pages. Import the Layout component and wrap your page content with it.

   jsxCopy code
   // pages/index.js
   import React from 'react';
   import Layout from '../components/Layout';
   
   const Home = () => {
     return (
       <Layout>
         <h1>Your Page Content Goes Here</h1>
         {/* Other page content */}
       </Layout>
     );
   };
   
   export default Home;
   

4. Import styles in your page or _app.js: Make sure to import your CSS module in your page or the _app.js file.

   jsxCopy code
   // pages/_app.js or pages/_app.jsx
   import '../styles/globals.css'; // Add any global styles
   import '../components/Layout.module.css'; // Import the Layout styles
   

   Now, your layout should have a sticky footer that stays at the bottom of the page, regardless of the content height.

Remember to customize the styles according to your design and add any additional content you need inside the Layout component.
