Understanding CSS classes in ReactJS Material UI componentsJust wanted to clarify some things

When it comes to styling Material UI components, the recommended approach is to utilize their useStyles function. Here's an example:

const useStyles = makeStyles(theme => ({
    root: {
        marginTop: '15px',
        display: 'flex',
        flexDirection: 'column',
        alignItems: 'center',
        flexGrow: '0'
    },
    menuButton: {
        color: grey[800],
    },
}));

However, you might be wondering why this method is preferred. What if you need to apply the same CSS to multiple components? Wouldn't it be more convenient to have a separate CSS file instead?

Answer №1

By exporting and reusing styles in other components, you can consolidate your CSS logic into a single makeStyles function, which can be stored in a centralized file for easy access.

  export const useStyles = makeStyles(themes => ({
    root: {
        marginTop: '15px',
        display: 'flex',
        flexDirection: 'column',
        alignItems: 'center',
        flexGrow: '0'
    },
    menuButton: {
        color: grey[800],
    },

  }));

There are several reasons why you might want to do this: for example, if you have a global theme that dictates using blue buttons but need to override with green for specific components while still maintaining inherited styles like fonts. This method allows for customization while staying consistent with the overall design.

This approach may be preferential, especially if your project follows a CSS in JS style and you want to avoid mixing traditional CSS. By encapsulating styles within components, you can enforce a more structured approach to styling in your library.

Essentially, this method involves taking themes as input and applying modifiers to customize the theme for components utilizing the useStyles class.

Furthermore, you can also apply these styles as a CSS class within your components for added flexibility.

Answer №2

Yes, you have the ability to import it into other files as needed.

For instance, if you require root style in a different View.jsx file, you can import useStyles into that file and utilize all of its classes within it.
