Enhancing React-Admin with custom Material-UI theme overrides for targeted CSS selectors on a global scale

When working with React-Admin, I encountered a challenge in applying specific CSS code globally within my Material UI theme. As I set up my theme, I included the following lines in the overrides section:

overrides: {
    "@global": {
        "[class*='RaLayout-content']": {
            overflow: "auto !important",
            maxWidth: "100vw !important",
        },
    },

Throughout the admin interface, there are multiple classes such as: RaLayout-content-4, RaLayout-content-221, RaLayout-content-31. These classes are generated by React-Admin, and I aim to apply the aforementioned CSS rules to every element containing the RaLayout-content class.

Due to class name minimization during Heroku deployment, I cannot include these CSS lines in my index.css file as they may not be effective post-minimization.

Prior to this, I had successfully implemented similar styles in my index.css file, albeit only functioning in development mode:

[class*="RaLayout-content"] {
  overflow: auto !important;
  max-width: 100vw !important;
}

I have also attempted to incorporate the MuiCssBaseLine without achieving the desired results.

Thank you for your assistance!

Answer №1

In my opinion, it is possible to customize the theme by using:

overrides: {
  RaLayout: {
    content: {
      // Add your customizations here
    },
  },
  ...
}
