Customizing PrimeReact Styles

I've been on a quest to find the perfect solution for customizing the default 'Nova' theme used in Prime React. While I know there is a theme designer available for purchase, I'd prefer not to go that route. In the past, I found myself cluttering my react application with a scss file for every tsx file, littered with !important tags like so -

.p-dropdown-trigger {
   background-color: brown !important;
   margin-left: 5px !important;
}

This led to a messy situation with excessive !important declarations scattered throughout. I contemplated commenting out the import for the Prime React theme in my index.tsx file

// import 'primereact/resources/themes/nova/theme.css';

And instead importing my own scss file..

import './styles/Override.scss';

However, this resulted in the styling disappearing completely and the page resembling plain HTML. I'm considering copying all the code from the Nova theme file and gradually tweaking it in the override file.

Does anyone have any better suggestions or ideas? Thanks

Answer №1

To streamline the process, you can consider duplicating all of the CSS code and then concealing their imports. This approach may require additional effort depending on the specifics of your project.

An alternative method would involve creating an override.scss file to selectively modify rules. Utilizing SCSS nesting can help keep things organized. To avoid the use of !important, it's advisable to target HTML elements more precisely. For example, if a CSS rule is defined as:

body header ul a { color: pink; }

you can create an overriding rule that is more specific:
body header ul li > a { color: blue; }

In cases where the rule you wish to overwrite contains !important, you will need to utilize !important in your new rule to enforce the change.

Answer №2

Perhaps with access to more code on codesandbox.io, I could offer greater assistance.

Have you explored modular CSS options like Styled-jsx or Styled-Components?

If you're considering styled-components, this resource on PrimeReact and styled-components may be useful: PrimeReact and styled-component

An alternative approach could involve linking the PrimeReact stylesheet before your own in the HTML. However, this solution would require a thorough analysis of the webpack's style implementation.

I hope this information proves helpful in some way :)

Subsequent CSS imports that follow the theme will take precedence over the templates because the final CSS rule holds greater specificity in CSS

In a create-react-app index.tsx (typescript .js) scenario, the index.css will override the initially imported prime themes, while CSS imports within the child React "App" component will not override the theme due to its prior import order. (Remember, the last relevant CSS rule applies unless overridden with !important.)

    import React from "react";
    import ReactDOM from "react-dom";
    import reportWebVitals from "./reportWebVitals";
    import App from "./App";
    
    import "../node_modules/primereact/resources/themes/saga-blue/theme.css";
    import "../node_modules/primereact/resources/primereact.min.css";
    import "../node_modules/primeicons/primeicons.css";
    
    import "./index.css";
    
    ReactDOM.render(
      <React.StrictMode>
        <App />
      </React.StrictMode>,
      document.getElementById("root")
    );

To ensure your React component's CSS (such as "App") takes precedence over React Prime theming, import the theme CSS first, followed by component-specific CSS imports to establish later and higher precedence.

    import "../node_modules/primereact/resources/themes/saga-blue/theme.css";
    import "../node_modules/primereact/resources/primereact.min.css";
    import "../node_modules/primeicons/primeicons.css";
    
    import React from "react";
    import ReactDOM from "react-dom";
    import reportWebVitals from "./reportWebVitals";
    import App from "./App";
    
    import "./index.css";
    
    ReactDOM.render(
      <React.StrictMode>
        <App />
      </React.StrictMode>,
      document.getElementById("root")
    );
