Customize elements such as MuiTab that rely on media queries

Looking to customize the font size for MuiTab using CSS overrides.

While following the material-ui documentation for CSS overrides, I successfully adjusted the font size for most elements. However, I encountered an issue with elements that utilize media queries, as they generate more specific CSS rules than my overrides.

In my theme.ts file:

import { createMuiTheme } from '@material-ui/core';

const fontSizeStyle = {
  fontSize: '1rem',
};

const fontFamilyStyle = {
  fontFamily: '"Ubuntu", sans-serif'
};

const theme = createMuiTheme({
  overrides: {
    MuiTab: {
      root: {
        ...fontFamilyStyle,
        ...fontSizeStyle,
      },
      label: fontSizeStyle,
    },
  }
});

export default theme;

The resulting CSS rules applied to a MuiTab are shown here.

The specific rule causing the trouble is located in this file: https://github.com/mui-org/material-ui/blob/master/packages/material-ui/src/Tab/Tab.js

[theme.breakpoints.up('md')]: {
  fontSize: theme.typography.pxToRem(13),
},

Is there a way to override this media query using the createMuiTheme function without knowing the breakpoints? Should I specify breakpoints in order to use them in my overrides?

Thanks in advance!

Answer №1

After some careful consideration, I was able to find a solution by defining it like this:

    MuiTab: {
      root: {
        minWidth: 0,
        '@media (min-width: 0px)': {
          minWidth: 0
        }
      }
    }

Provide the following specifications:

let customTheme = createMuiTheme({});

customTheme = {
  ...customTheme,
  overrides: {
    MuiTab: {
      root: {
        [customTheme.breakpoints.up("xs")]: {
          minHeight: 10
        }
      }
    }
  }
}

export default customTheme;

theme.breakpoints provides access to four helper functions for creating CSS media queries:

theme.breakpoints.up(key)
theme.breakpoints.down(key)
theme.breakpoints.only(key)
```
theme.breakpoints.between(start, end)
```

Each key corresponds to a breakpoint and aligns with a specific screen width. Valid key values are xs|sm|md|lg|xl

I encountered a similar issue myself. After reading up on Breakpoints, I was able to find a workaround for this situation. However, I found it somewhat cumbersome having to apply the overridden styles individually to each Tab using the classes property.

Important: I haven't figured out how to solve this problem using the createMuiTheme function yet

To implement the style within the breakpoints style, you can do the following:

const styles = theme => ({
  mediaFont:{
    [theme.breakpoints.up('md')]: {
     fontSize:fontSizeStyle.fontSize,
    },
  },
  });

Apply the above style to TabLabel

<Tab label="Item One" classes={{label:classes.mediaFont}} />

One way CSS can prioritize styles is through the use of !important, allowing less specific rules to override more specific ones.

const customFontSize = {
  fontSize: '1rem !important',
};
