Sustainable React Components

This is a sustainable React component project based on greenCSS. The components work with plain React, as well as with SSR - such as Next.js. Animations and the basic design were realised with greenCSS. greenCSS is an animated, responsive, lightweight and sustainable CSS library. It is recommended that you also use greenCSS in your project. If you don't want to, just style your modal with your own classes.

The project is based on the sustainable-react package.

How to use the Accordion

Accordion Features

• Tested with react and next.js
• Press Tab + Enter to open the accordions
• Two different styles out of the box, or use your own classNames

The example below uses greenCSS for styling. Download greenCSS or learn more on the greenCSS website. Alternatively to greenCSS you can insert your own classNames. The Accordion can be operated with the keyboard (Tab / Enter) as well as clicked.

Accordion Example

1import React from 'react'
2import { Accordion } from 'codn'
3// import the styles
4import 'codn/dist/style/green.css'
5// if you want to use the greencss classNames:
6import 'greencss/css/greencss.css'
7
8export default function AccordionComponent() {
9  return (
10    <div className='sans m-auto bg-gray-10 w-60rem rounded-20px shadow-small-gray-9'>
11      <div className='w-50rem m-auto py-50px'>
12        // default Accordion
13        <Accordion
14          className='bg-white rounded-5px'
15          expand='first title'
16          collapse='collapsed content'
17          headerStyleExpanded='text-15px font-600 text-purple pb-10px'
18          iconColorExpanded='stroke-purple'
19        />
20        // Boxed Accordion
21        <Accordion boxStyle={true} expand='second title' collapse='second collapsed content' />
22      </div>
23    </div>
24  )
25}

Accordion Props

You can adjust the default values listed below at any time with your values or classNames. Be aware that you may have to readjust the design. Therefore, a change is only recommended if you really know what you are doing.

Name	Default Value	Description
expand	'Your title'	Your title
collapse	'Your collapsed content'	Your collapsed content
className	'bg-white'	Use your own className to style the Accordion
boxStyle	false	Secondary Accordion design
shadow	true	Set a shadow around the secondary icon
headerStyle	'text-15px font-600 text-black'	Default "expand" title design
collapseStyle	'text-15px text-black'	Default text style for collapsed content
headerStyleExpanded	'text-15px font-600 text-blue pb-10px'	Default "expand" title design if expanded
iconColorCollapse	'stroke-black'	Default icon className if collapsed
iconColorExpanded	'stroke-blue'	Default icon color if expanded
circleCollapse	'shadow-small-gray-10 bg-white'	Default circle color around the boxStyle icon if collapsed
circleExpand	'rotate-90deg bg-blue'	Default circle color around the boxStyle icon if expanded
border	' border = 'focus:outline-1px focus:outline-solid focus:text-blue-9 text-blue-9 border-1px border-solid border-gray-10''	Default border style

How to use the Modal

Modal Features

• Tested with react and next.js
• Press CTRL + k to open the modal
• Press ESC key to close the modal
• On Chrome browser the background is blurred. In Firefox this feature is not available, there the background has an opacity of 75%.
• Click on the background or the close icon (top right corner) to close the modal.
• The Modal component use a default greenCSS fade in animation with a duration of 500ms fade-in animation-duration-500ms animation-forwards. If you want to animate the Modal.Header or Modal.Body, just add your greenCSS or your custom animation as a class to the className. Here can find all greenCSS animations. p.e. <Modal.Body className='clip-circle-in-left animation-duration-800ms animation-forwards'>
• Do you want to use your own close icon on the top right corner? Add closeIcon with your own (svg-) component. <Modal toggle={toggleModal} setToggle={setToggleModal} closeIcon={<div>X</div>}> The recommended size for an svg is 20x20px.
• People who do not want animations will automatically not be shown any motions. As it will be blocked by default prefers-reduced-motion: reduce

Modal Example

Next.js installation

In the pages directory, add _document.js. It is important to add <div id='modal-portal' /> below the <Main /> component. Otherwise your SSR Modal will not work. Learn more about the custom document.

1// pages/_document.js
2import Document, { Html, Head, Main, NextScript } from 'next/document'
3
4class MyDocument extends Document {
5  static async getInitialProps(ctx) {
6    const initialProps = await Document.getInitialProps(ctx)
7    return { ...initialProps }
8  }
9
10  render() {
11    return (
12      <Html>
13        <Head />
14        <body>
15          <Main />
16          <div id='modal-portal' />
17          <NextScript />
18        </body>
19      </Html>
20    )
21  }
22}
23export default MyDocument

The following jsx file below is based on greenCSS. If you don't want to use it, you can add your own classNames.

1import React, { useState } from 'react'
2import { Modal } from 'codn'
3// import the styles
4import 'codn/dist/style/green.css'
5
6export default function Home() {
7  const [toggleModal, setToggleModal] = useState(false)
8  return (
9    <div className='min-h-100vh bg-gray-9'>
10      {/* Modal Toggle Button */}
11      <button onClick={() => setToggleModal((prev) => !prev)} className='bg-red-9 px-20px py-10px rounded-10px hover:bg-red-7'>
12        Toggle Modal
13      </button>
14
15      {/* Modal */}
16      <Modal toggle={toggleModal} setToggle={setToggleModal}>
17        <Modal.Header className='sans font-900 text-30px fade-in-left animation-duration-500ms animation-forwards'>
18          <h3>👋 Hi, I'm your modal</h3>
19        </Modal.Header>
20        <Modal.Body className='sans font-400 text-15px text-gray fade-in animation-duration-800ms animation-forwards'>
21          <p>

34        </Modal.Footer>
35      </Modal>
36    </div>
37  )
38}

Do you want to use your style within the modal? No problem - you can add any JSX inside.

1import React, { useState } from 'react'
2import { Modal } from 'codn'
3// import the styles
4import 'codn/dist/style/green.css'
5
6export default function Home() {
7  const [toggleModal, setToggleModal] = useState(false)
8  return (
9    <div className='min-h-100vh bg-gray-9'>
10      {/* Modal Toggle Button */}
11      <button onClick={() => setToggleModal((prev) => !prev)} className='bg-red-9 px-20px py-10px rounded-10px hover:bg-red-7'>
12        Toggle Modal
13      </button>
14
15      {/* Modal */}
16      <Modal toggle={toggleModal} setToggle={setToggleModal}>
17        <h3>👋 Hi, I'm your independent modal</h3>
18        <p>
19          Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna
20          aliqua. Viverra accumsan in nisl nisi scelerisque eu ultrices vitae auctor. Quis vel eros donec ac. Mauris pellentesque
21          pulvinar pellentesque habitant morbi tristique senectus.
22        </p>
23      </Modal>
24    </div>
25  )
26}

React installation

You can also use the codn modal in your create-react-app. Head to your public/index.html file and add <div id="modal-portal" /> below the <div id="root"></div>.

1<!DOCTYPE html>
2<html lang="en">
3  <head>
4    <meta charset="utf-8" />
5    <link rel="icon" href="%PUBLIC_URL%/favicon.ico" />
6    <meta name="viewport" content="width=device-width, initial-scale=1" />
7    <meta name="theme-color" content="#000000" />
8    <meta name="description" content="Web site created using create-react-app" />
9    <link rel="apple-touch-icon" href="%PUBLIC_URL%/logo192.png" />
10    <link rel="manifest" href="%PUBLIC_URL%/manifest.json" />
11    <title>React App</title>
12  </head>
13  <body>
14    <noscript>You need to enable JavaScript to run this app.</noscript>
15    <div id="root"></div>
16    <div id="modal-portal" />
17  </body>
18</html>

Within a page or a component, you can now add and use the Modal.

1import React, { useState } from 'react'
2import { Modal } from 'codn'
3// import the styles
4import 'codn/dist/style/green.css'
5
6function App() {
7  const [toggleModal, setToggleModal] = useState(false)
8  return (
9    <div className='App'>
10      {/* Modal Toggle Button */}
11      <button onClick={() => setToggleModal((prev) => !prev)} className='bg-red-9 px-20px py-10px rounded-10px hover:bg-red-7'>
12        Toggle Modal
13      </button>
14
15      {/* Modal */}
16      <Modal toggle={toggleModal} setToggle={setToggleModal}>
17        <Modal.Header className='sans font-900 text-30px fade-in-left animation-duration-500ms animation-forwards'>
18          <h3>👋 Hi, I'm your modal</h3>
19        </Modal.Header>
20        <Modal.Body className='sans font-400 text-15px text-gray fade-in animation-duration-800ms animation-forwards'>
21          <p>
22            Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna

24            pellentesque pulvinar pellentesque habitant morbi tristique senectus.
25          </p>
26        </Modal.Body>
27        <Modal.Footer className='sans font-400 text-10px'>
28          <h3>copyright</h3>
29        </Modal.Footer>
30      </Modal>
