How to add floating action button on the right-bottom side of the screen using material ui in react

Question

I am trying to add FloatingActionButton on right bottom side of the screen. I am using this library http://www.material-ui.com/#/components/floating-action-button

import React, { Component } from "react";
import logo from "./logo.svg";
import "./App.css";

import AppBar from "material-ui/AppBar";
import FloatingActionButton from "material-ui/FloatingActionButton";
import MuiThemeProvider from "material-ui/styles/MuiThemeProvider";
import * as strings from "./Strings";
import styles from "./Styles";
import ContentAdd from "material-ui/svg-icons/content/add";

const AppBarTest = () =>
  <AppBar
    title={strings.app_name}
    iconClassNameRight="muidocs-icon-navigation-expand-more"
  />;

class App extends Component {
  render() {
    return (
      <MuiThemeProvider>
        <div>
          <AppBarTest />
          <FloatingActionButton style={styles.fab}>
            <ContentAdd />
          </FloatingActionButton>
        </div>

      </MuiThemeProvider>
    );
  }
}

export default App;

Styles.js

const style = {
    fab: {
        backgroundColor: '#000000'
    },
};

export default style;

Question 1

It is showing FloatingActionButton on top-left side, I want to make this on right-bottom side. What is the way to do this ?

Question 2

Why style is not applying on FloatingActionButton ?

Answer 1

Try this style:

const fabStyle = {
    right: 20,
    position: 'fixed'
};

and later u use margin, top... but don't use auto on position: fixed
