CSS in JS is great, but how do you handle the convenience of handling Pseudo-classes? react-dom-pseudo provides a component like the react-motion method, conveniently a react-dom object Provide pseudo-classes like CSS.

We first install with npm:

$ npm install --save react-dom-pseudo

APIs

react-dom-pseudo following pseudo-classes are supported：

Will merge with all styles and override duplicate style properties

Props Analog pseudo-class Description Default Value Is Must
merge Whether to merge with style and otherStyles true No
disable Whether to cancel the event listener false No
style Style of default undefined No
linkStyle :link Style of not clicked before undefined No
visitedStyle :visited Style of that has been clicked undefined No
focusStyle :focus Style of type element such as input onFocus undefined No
hoverStyle :hover Style of displayed when the mouse is moved in undefined No
activeStyle :active Style of when mouse or touch screen clicks undefined No
disableStyle Style of when disable event listener undefined No
alwayStyle Merge with all styles undefined No

They will trigger based on the event，and merge style， like {...style, ...activeStyle}

Only existing styles will be merged

Combination rules for styles: {...style, ...linkStyle, ...eventStyle, ...disableStyle, ...alwayStyle}

Use

import Pseudo from 'react-dom-pseudo';

export default () => {
  return (
    <div>
      <div>example:</div>
      <Pseudo
        style={sheet.input}
        hoverStyle={sheet.inputHover}
        focusStyle={sheet.inputFocus}
      >
        {events => <input {...events} />}
      </Pseudo>
    </div>
  );
};

// CSS in js
const sheet = {
  input: {
    fontSize: '14px',
    border: '1px solid rgba(0,0,0,0)',
    background: '#f3f3f3',
    // use transition animate
    transition: 'all 0.2s ease-out',
  },
  inputHover: {
    background: '#f0f0f0',
  },
  inputFocus: {
    border: '1px solid rgba(0,0,0,0.1)',
    background: '#f0f0f3',
    transitionTimingFunction: 'ease-in',
  },
};

What did it do?

Pseudo's renderProps contains the following events:

  • onClick: Used to simulate :link & :visited
  • onFocus\Blur: Used to simulate :focus
  • onMouseEnter\Leave: Used to simulate :hover
  • onMouseDown\Up: Used to simulate :active

If the project is executed on the mobile side, it will onMouse? changeTo onTouch?
