React MUI Fab API

MUI or Material-UI is a UI library providing predefined robust and customizable components for React for easier web development. The MUI design is based on top of Material Design by Google.

In this article, we will discuss the React MUI Fab API. The FAB or Floating Action Button is used as a button that provides quick navigation to the most accessed area of the website. The API provides a lot of functionality and we will learn to implement them.

// or
import { Fab } from '@mui/material';

Example 1: In the following example, we have an enabled Fab and another disabled Fab.

App.js

import "./App.css";
import * as React from "react";
import Box from "@mui/material/Box";
import Fab from "@mui/material/Fab";
import AddIcon from "@mui/icons-material/Add";
import EditIcon from "@mui/icons-material/Edit";
import FavoriteIcon from "@mui/icons-material/Favorite";
import NavigationIcon from "@mui/icons-material/Navigation";
import { Html } from "@mui/icons-material";

function App() {
    return (
        <div className="App">
            <div
                className="head"
                style={{
                    width: "fit-content",
                    margin: "auto",
                }}
            >
                <h1
                    style={{
                        color: "green",
                    }}
                >
                    GeeksforGeeks
                </h1>
                <strong>React MUI Fab API</strong>
            </div>
            <br />
            <Box
                sx={{
                    margin: "auto",
                    display: "flex",
                    justifyContent: "space-evenly",
                    width: "50%",
                }}
            >
                <Fab color="primary"
                    aria-label="add">
                    <AddIcon />
                </Fab>

                <Fab disabled aria-label="Html">
                    <Html />
                </Fab>
            </Box>
        </div>
    );
}
export default App;

Output:
