A guide on implementing CSS and Styling in a React component

Struggling to style my React.js file that was converted from a standard web page. I have the original CSS but unsure how to use React for proper styling. Any assistance is welcomed!

var NavBar = React.createClass({
  render: function() {
    return (
      /* Styling the Navbar */
      <div className="dark_bg_color">
        // Rest of the code
      </div>
    );
  }
});
ReactDOM.render(<NavBar />, document.getElementById('nav'));

// More code blocks for Gallery, What's New, Events, iOS and Footer components.

Answer №1

After reading your query, it appears that there may be an issue with your current CSS not functioning properly when transitioning to a React-based webpage.

It is expected to work, but if it isn't, there might be other underlying factors that need to be addressed for resolution. I personally transitioned one of my projects to React while maintaining the same CSS file without any problems.

However, if you are seeking the most optimal approach...

As suggested by others, React tends to favor inline styles. Yet, in my opinion, this method can lead to messiness, difficulty in modifications, and overall complexity.

Utilizing SCSS or LESS for styling in React is highly recommended.

Here's why:

Your Styles Are Reusable

While inline styling may be suitable for a few components, reusing the same styles becomes cumbersome as more components are added.

Easier to Update

By using separate CSS files, updating styles for specific components becomes more straightforward compared to sifting through React code.

Avoids Overwriting Issues

Inline styles take precedence over all other styles, creating challenges in troubleshooting larger applications.

Consistent Styling Across Platforms

Adopting SCSS & LESS ensures consistent styling practices across different frameworks, eliminating the need to adjust for each platform.

Although inline styles may work well within React, it may pose limitations when switching to other frameworks. Instead of reinventing the wheel, sticking to conventional CSS methods provides versatility across various platforms.

To maintain a compartmentalized approach, consider creating a separate .scss file for each specific component you are styling and then importing it into your component file.

For example:

Directory Structure:

components
|
|--Card
   |
   |--Card.js
   |--Card.scss
   |--index.js
|--Another Component Folder

Card.js:

import React, { Component } from 'react';
import classes from './Card.scss';

export class Card extends Component {

    render () {
        return (
            <div className={`${classes.layout} col`}>
                <div className={`${classes.card} card`}>
                    <div className="card-image">
                        <ProviderImage />
                    </div>
                </div>
            </div>
        );
    }
}

export default Card;

Card.scss:

.layout {
    img {
        display: block;
        max-width: 372px;
        max-height: 372px;
        height: auto;
        width: auto;
    }
}

.card {
    width: 370px;
    height: 550px;
}

By following this structure, the styles remain contained within their respective components.

                        <ProviderImage />
                    </div>
                </div>
            </div>
        );
    }
}

export default Card;

Card.scss:

.layout {

        display: block;
        max-width: 372px;
        max-height: 372px;
        height: auto;
        width: auto;
    }
}

.card {
    width: 370px;
    height: 550px;
}

By following this structure, the styles remain contained within their respective components.

One way to incorporate CSS into your HTML document is by placing it in the <head> section just like a regular CSS file. As long as your React components use the same classes (but with className instead of class) it should function properly.

For a more modern, JavaScript-focused approach, consider exploring CSS Modules. You can learn more about them at this link:

https://css-tricks.com/css-modules-part-1-need/

Keep in mind that the latter method may come with a steeper learning curve.

According to Vijay, React shows a preference for inline styles.

A common approach is to create a single styles object within each Component, containing all the necessary styles, like this:

var styles = {
  navBar: {
    backgroundColor: 'dark blue'
  },
  center: {
    textAlign: 'center'
  },
  rightNav: {
  },
  verticalLine: {
  },
};

var NavBar = React.createClass({
  render: function() {
    return (
      <div style={styles.navBar} >
        <img src="logo.png" />
        <div style={styles.center} >
          <div>
            <ul>
              <li>daily specials</li>
              <li>gift gallery</li>
              <li>events</li>
              <li><i className="fa fa-search" />&nbsp;search</li>
            </ul>
          </div>
        </div>
        <div style={styles.rightNav}>
          <div style={styles.center}>
            <div>
              <button type="button">Sign Up</button>
              <button type="button">Log In</button>
              <div style={styles.verticalLine} >&nbsp;</div>
              <button type="button">Cart</button>
            </div>
          </div>
        </div>

Utilizing Sass allows for nesting CSS selectors to mirror the hierarchical structure of your HTML, enhancing readability and organization. However, it is important to be cautious of excessive nesting, as it can lead to overly qualified CSS that may become difficult to maintain and is generally discouraged. To illustrate this point, consider the following example.

ExampleComponent.jsx

import "./ExampleComponent.scss";

import React, { Component } from "react";

class ExampleComponent extends Component {
  render() {
    return (
      <div className="example-component">
        <span className="example-header">Sass simplifies styling.</span>
      </div>
    );
  }
}

export default ExampleComponent;

ExampleComponent.scss

.example-component {
    .example-header {
        <!-- Custom styles for header -->
    }

    .other-class {}
}

Answer №6

One important step is to ensure your CSS or SCSS files are properly imported, preferably using the direct path method:

import "components/card/card";

To enable this functionality, make sure you have SASS loaders and webpack configured in your project.

Your webpack.config file should include the following setup for sass loaders:

  module: {
    loaders: [
      {test: /\.scss$/, loaders: ["style", "css", "sass"]},
      {test: /\.css$/, loader: ExtractTextPlugin.extract("style-loader", "css-loader")},
      {test   : /\.woff|\.woff2|\.svg|.eot|\.ttf|\.png/, loader : 'url?prefix=font/&limit=10000&name=/assets/fonts/[name].[ext]'
      }
    ]

It's recommended to use the "sass-loader": "^3.0.0",

For Windows users, a workaround is needed for the loader to function properly. Here are some steps:

Show hidden files in the folder options.
Navigate to the folder 'user/appData', typically located at: C:\Users\user\AppData\Roaming\npm
Add the windows environment variable: NODE_PATH C:\Users\user\AppData\Roaming\npm\nodeModules
Execute the command npm install -g
Close and reopen the command prompt.

By following these steps, you'll be able to load and compile sass with webpack, especially beneficial when working with React applications.

I prefer using Sass for styling my React components, specifically the .scss syntax. In addition to Sass, I have also implemented PostCSS to further enhance my styles. Both of these technologies are utilized in a modularized way. Setting them up through webpack in my workflow has made it easy to style my React app. All I need to do is import the style.scss file (yes, with .scss extension) into my index.js file, which is located in the root directory alongside App.js. This is where everything necessary for the app to function is kept. Below is an example snippet from the React app I am currently developing:

Index.js:

import React from 'react';
import ReactDOM from 'react-dom';
import 'core-js/es6/map';
import 'core-js/es6/set';
import App from './App';
import './favicon.ico';
import './style/style.scss';

ReactDOM.render(
    <App />, document.getElementById('root')
);
