Question

Creating a <Box /> component in MaterialUI with styled components is a great way to customize the design and layout of your

@material-ui/styles offers a different way to customize default styles:

import React from 'react';
import Box from '@material-ui/core/Box';
import { styled } from '@material-ui/core/styles';


const StyledBox = styled(Box)({
  color: 'red'
});

With Box behaving like <div /> by default, we can change it by passing the component prop:

// somewhere in code
<StyledBox 
  component="span" 
>
  Some text
</StyledBox>

However, trying to define a component for Box while styling like below will not work:

import React from 'react';
import Box from '@material-ui/core/Box';
import { styled } from '@material-ui/core/styles';


const StyledBox = styled(<Box component="span" />)({
  color: 'red'
});

Is there a method to set a component definition for Box during the styling phase using styled?

To demonstrate how to achieve this, consider the following example. It is not possible to directly pass <Box component="span" /> (an element) to the styled function because it requires a component type rather than an element (i.e., an instance of a component). Therefore, you must create a new component type (SpanBox in the example below) that encapsulates Box, transfers any props or ref, and specifies the desired properties (e.g., component="span").

import React from "react";
import Box from "@material-ui/core/Box";
import { styled } from "@material-ui/core/styles";

const StyledBox = styled(Box)({
  color: "red"
});

const SpanBox = React.forwardRef(function SpanBox(props, ref) {
  return <Box ref={ref} component="span" {...props} />;
});
const StyledSpanBox = styled(SpanBox)({
  color: "purple"
});

export default function App() {
  return (
    <div className="App">
      <StyledBox>red div 1</StyledBox>
      <StyledBox>red div 2</StyledBox>
      <StyledSpanBox>purple span 1</StyledSpanBox>
      <StyledSpanBox pl={3} border={1}>
        purple span 2
      </StyledSpanBox>
    </div>
  );
}
