React component Material UI withStyles: Variables in styles?












1















Is there a way to use variables in my React components using Material UI and withStyles? How can replace the repeated '20px' in the styles const below with a variable? Is this possible?



import React, { Component } from 'react';
import { withStyles } from '@material-ui/core/styles';
import Topnav from '../component/Topnav';
import Footer from '../component/Footer';

const styles = {
root: {
flexGrow: 1,
},
grow: {
flexGrow: 1,
},
margin: {
marginLeft: '20px',
marginRight: '20px',
marginTop: '20px',
}
};

class MainLayoutComp extends Component {
render = props => {
const { children, classes } = this.props;

return (
<>
<Topnav />
<div className={classes.margin}>
{children}
<Footer />
</div>
</>
);
}
}

const MainLayout = withStyles(styles)(MainLayoutComp);
export default MainLayout;

          It's just JavaScript, so you can do the following:



          const myMargin = '20px';
          const styles = {
          root: {
          flexGrow: 1,
          },
          grow: {
          flexGrow: 1,
          },
          margin: {
          marginLeft: myMargin,
          marginRight: myMargin,
          marginTop: myMargin,
          }
          };


          Also, you can easily leverage your theme by using a function for the styles. withStyles will pass the theme as an argument:



          const styles = (theme) => ({
          root: {
          flexGrow: 1,
          },
          grow: {
          flexGrow: 1,
          },
          margin: {
          marginLeft: theme.spacing.unit * 3,
          marginRight: theme.spacing.unit * 3,
          marginTop: theme.spacing.unit * 3,
          }
          });
