Introduction

When developing a web application using React and Next.js, and utilizing Material UI for UI components, it's not uncommon to encounter issues with custom styles defined via the sx prop. In this article, we'll delve into a specific problem where the border color defined via the sx prop shows correctly in DevTools but not on the rendered site.

Problem Description

You're developing a web application using React and Next.js, and you're using Material UI for your UI components. You have a component that renders a Material UI Card with custom styles via the sx prop. However, when you inspect the component in DevTools, the border color defined via the sx prop is displayed correctly. However, when you view the rendered site, the border color is not visible.

Additional Information

You've tried the following:

  • Inspecting the component in DevTools to ensure the styles are being applied correctly.
  • Checking the CSS rules in the browser's DevTools to see if there are any conflicts or overriding styles.
  • Verifying that the sx prop is being passed correctly to the Material UI Card component.
  • Reviewing the Material UI documentation to ensure you're using the sx prop correctly.

Possible Causes

There are several possible causes for this issue:

  • CSS specificity: The styles defined via the sx prop may be overridden by other CSS rules in the application.
  • Material UI theme: The Material UI theme may be overriding the styles defined via the sx prop.
  • Browser rendering: The browser may not be rendering the styles defined via the sx prop correctly.

Solution

To resolve this issue, you can try the following:

1. Check CSS Specificity

  • Inspect the CSS rules in the browser's DevTools to see if there are any conflicts or overriding styles.
  • Use the browser's DevTools to identify the CSS rules that are overriding the styles defined via the sx prop.
  • Adjust the CSS specificity of the styles defined via the sx prop to ensure they take precedence over other CSS rules.

2. Verify Material UI Theme

  • Review the Material UI documentation to ensure you're using the sx prop correctly.
  • Verify that the Material UI theme is not overriding the styles defined via the sx prop.
  • Adjust the Material UI theme to ensure it's not overriding the styles defined via the sx prop.

3. Browser Rendering

  • Verify that the browser is rendering the styles defined via the sx prop correctly.
  • Use the browser's DevTools to identify any issues with the browser rendering the styles defined via the sx prop.
  • Adjust the browser rendering settings to ensure it's rendering the styles defined via the sx prop correctly.

Example Code

Here's an example code snippet that demonstrates how to use the sx prop to define custom styles for a Material UI Card component:

import React from 'react';
import { Card, CardContent } from '@mui/material';

const CustomCard = () => {
  return (
    <Card
      sx={{
        backgroundColor: 'primary.main',
        color: 'primary.contrastText',
        border: '1px solid',
        borderColor: 'primary.main',
      }}
    >
      <CardContent>Custom Card Content</CardContent>
    </Card>
  );
};

export default CustomCard;

In this example code snippet, we're defining custom styles for a Material UI Card component using the sx prop. We're setting the background color, text color, border, and border color using the sx prop.
