Having difficulty customizing the icon within the Alert component in Material UI for React by utilizing an external CSS file

I'm struggling to get my code to work properly. I'm currently using MUI to style my components with a separate CSS file. I'm attempting to style an Alert component, specifically focusing on the alert icon, but I'm having trouble getting it to work.

Here's the JSX component:

<Alert severity='error' className='passwordAlert'>
    Invalid Password
</Alert>

And here's the working CSS component:

.passwordAlert {
    border-radius: 100px;
    width: 80%;
    margin-bottom: 0%;
    margin-top: 1%;
    height: 50px;
    padding: 0px;
    align-items: center;
}

However, the following CSS component isn't working as expected:

.passwordAlert.MuiAlert-icon {
    padding-left: 5%;
}

I prefer to keep my styles in a separate file, and even though I'm aware of other styling methods, I'm wondering if there's a solution using className and a separate CSS file.

Thank you for any assistance you can provide.

Answer №1

When trying to combine selectors, keep in mind that MuiAlert-icon and .passwordAlert are not within the same element. Therefore, create separate CSS rules for MuiAlert-icon.

Answer №2

Avoid creating individual files for customizing MUI components. MUI offers several methods for customization. Check out the guide on Customizing MUI components for more information.
