How to make a sticky footer in react?

Much easier idea (following the trend), i imported both bootstrap and reactstrap, used the bootstrap fixed bottom class and workaround with that like this.

class AppFooter extends Component{
render() {
    return(
        <div className="fixed-bottom">  
            <Navbar color="dark" dark>
                <Container>
                    <NavbarBrand>Footer</NavbarBrand>
                </Container>
            </Navbar>
        </div>
    )
}

There is a much simpler way. I am creating a portfolio site with React, and some of my pages are not very long, so in some devices, like kindle fire hd for example, the footer would not stick to the bottom. And of course to set this up in the traditional fashion with would not work, because the would be wrapped in there. And we don't want that. So this is what I did:

In App.js:

import React, { Component } from 'react';
import {Header} from './components/Header';
import {Main} from './components/Main';
import {Footer} from './components/Footer';

class App extends Component {
    render() {
        return (
            <div className="App Site">
                <div className="Site-content">
                    <div className="App-header">
                        <Header />
                    </div>
                    <div className="main">
                        <Main />
                    </div>
                </div>
                <Footer />
            </div>
        );
    }
}

export default App;

And then in _sticky-footer.css (I use POSTCSS):

:root {
    --space: 1.5em 0;
    --space: 2em 0;
}

.Site {
    display: flex;
    flex-direction: column;
    min-height: 100vh;
}

.Site-content {
    flex: 1 0 auto;
    padding: var(--space) var(--space) 0;
    width: 100%;
}

.Site-content:after {
    content: '\00a0';
    display: block;
    margin-top: var(--space);
    height: 0;
    visibility: hidden;
}

The original solution for this was created by Philip Walton: https://philipwalton.github.io/solved-by-flexbox/demos/sticky-footer/

You can fix this by adding margin-bottom: 60px; to the body of your website. With the 60px being the height of your footer.

Here's an idea (sandbox example link).

Include a phantom div in your footer component that represents the footer's position that other dom elements will respect (i.e. affecting page flow by not being position: 'fixed';).

var style = {
    backgroundColor: "#F8F8F8",
    borderTop: "1px solid #E7E7E7",
    textAlign: "center",
    padding: "20px",
    position: "fixed",
    left: "0",
    bottom: "0",
    height: "60px",
    width: "100%",
}

var phantom = {
  display: 'block',
  padding: '20px',
  height: '60px',
  width: '100%',
}

function Footer({ children }) {
    return (
        <div>
            <div style={phantom} />
            <div style={style}>
                { children }
            </div>
        </div>
    )
}

export default Footer
