CSS styles

The framework supports the following styles by default

  • Css Basic CSS style support
  • Scss A popular CSS preprocessor that extends CSS with features such as variables, nested rules, and mixins
  • Module.scss Create modular CSS classes to avoid naming conflicts and improve maintainability
  • CSS-in-JS Use JavaScript to write CSS styles

Configure global styles

  • You can import css or sass in the layout.js file to configure global styles
  • Use Module.scss to prevent style conflicts
  • Execute npm i @emotion/styled in the terminal to install @emotion/styled

import './compontents/global.scss';
export default (props)=>{  
    return (
      <html lang="en">
        <head>
          <title>style</title> 
        </head>

            <div><a href="/style/index">to app index</a></div>
            <div><a href="/style/about">to app about</a></div>
            <div><a href="/style/contact">to app contact</a></div>
            {props.children}
        </body>

}

export default ()=>(
    <h1>index</h1>
)

import Style from './compontents/about.module.scss'
export default ()=>(
    <div className={Style.root}>
        <h1>about</h1>
    </div>
)

import Style from './compontents/contact.style.js'
export default ()=>(
    <Style>contact</Style>
)

h1 {
    color: red;
}

.root{
    :global{
        h1{
            color: green;
        }
    }
}

import Styled from '@emotion/styled';
export default (props)=>{
    const Style = Styled.h1({ 
        color:'blue'
    });
    return <Style>{props.children}</Style>
}

  • In the above example, global.scss is imported into layout.js and the global style of the h1 tag is defined as red. Then, about.module.scss is imported into about.js to define the style of h1 of the current page as green. contact.style.js is imported into contact.js and the style of h1 is defined as blue.
