Tips on adding CSS to a React component

I've successfully converted an HTML file into a component designed to resemble a 7-segment LED display. I have imported the necessary CSS styles from the index.css file, but I am unsure how to properly apply these styles within the component.

My attempts to inject the styles through specific values have not yielded the desired results, as the CSS syntax seems to be causing compatibility issues with my component. I am seeking guidance on whether there is a method to pass these styles without needing to make modifications to the original CSS file.

import React from 'react'
import styles from './index.css'

const Display = () =>{
  return(
    <div id="vertical-center">
        <div id="clock-container">
            <div id="display-1" className="display-container display-size-12 display-no-0">
                <div className="segment-x segment-a"><span className="segment-border"></span></div>
                <div className="segment-y segment-b"><span className="segment-border"></span></div>
                <div className="segment-y segment-c"><span className="segment-border"></span></div>
                <div className="segment-x segment-d"><span className="segment-border"></span></div>
                <div className="segment-y segment-e"><span className="segment-border"></span></div>
                <div className="segment-y segment-f"><span className="segment-border"></span></div>
                <div className="segment-x segment-g"><span className="segment-border"></span></div>
            </div>
        </div>
    </div>
  )
}

export default Display

Any recommendations on injecting/styling elements using this index.css:

.clear {
    clear: both;
}
...
#clock-container {
    margin-top: -110px;
    ...
}

Answer №1

It is advisable to utilize the style attribute with curly brackets instead of the className attribute...

Answer №2

Simply include the following line in your component file:

import './index.css'

This will automatically apply all styles to your component.

Answer №3

If you're looking to easily inject CSS into components, check out the handy JS framework called classnames.

import classnames from 'classnames/bind'
import styles from './index.css'
const cx = classnames.bind(styles)

With this framework, applying CSS is a breeze:

<div className={cx('divClass')}>
</div>

You can even apply multiple classes like so:

<div className={cx(['firstClass','secondClass'])}>
</div>
