SASS Applies style to the whole website despite only imported into a single page

2G1P

I’m trying to apply a SASS file on one single js page, but the import goes on the whole website.

Here is my partner.sass file :

html,
body,


.media article,img p
  animation-name: fade-in
  animation-fill-mode: both
  animation-duration: 1.5s


@for $i from 1 to 60
  .media article:nth-child(#{$i})  
      animation-delay: $i * 0.1s

@keyframes fade-in
    0%
        opacity: 0
    100%
        opacity: 1

and here is my partner.js file :

import React from 'react'
import PropTypes from 'prop-types'
import { graphql } from 'gatsby'
import Layout from '../components/Layout'
import Content, { HTMLContent } from '../components/Content'
import '../components/partner.sass'

export const PartnerPageTemplate = ({ title, content, contentComponent }) => {
  const PageContent = contentComponent || Content

  return (
    <section className="section section--gradient">
      <div className="container">
        <div className="columns">
          <div className="column is-10 is-offset-1">
            <div className="section">
              <h2 className="title is-size-3 has-text-weight-bold is-bold-light">
                {title}
              </h2>
              <PageContent className="content" content={content} />
              
            </div>
          </div>
        </div>
      </div>
    </section>
  )
}

PartnerPageTemplate.propTypes = {
  title: PropTypes.string.isRequired,
  content: PropTypes.string,
  contentComponent: PropTypes.func,
}

const PartnerPage = ({ data }) => {
  const { markdownRemark: post } = data

  return (
    <Layout>
      <PartnerPageTemplate
        contentComponent={HTMLContent}
        title={post.frontmatter.title}
        content={post.html}
      />
    </Layout>
  )
}

PartnerPage.propTypes = {
  data: PropTypes.object.isRequired,
}

export default PartnerPage

export const partnerPageQuery = graphql`
  query PartnerPage($id: String!) {
    markdownRemark(id: { eq: $id }) {
      html
      frontmatter {
        title
      }
    }
  }

Whenever I refresh or try to switch to another page, everything (which I believe is due to html and body tags from my sass file) is fading (although I just wanted my articles from the markdown page to fade-in) Is there anyway SASS can apply and handle only one js page instead of all my components ?

Thank you

Answer

Just use CSS Modules as stated in the DOCS https://www.gatsbyjs.com/docs/how-to/styling/css-modules/ and for the rest which is global, keep using global css.

Sample:

  1. Rename your style file to partner.module.sass and import as such
  2. Rename rules with double dash (section–gradient) to camelCase (sectionGradient)
...
import * as styles from '../components/partner.module.sass'

export const PartnerPageTemplate = ({ title, content, contentComponent }) => {
  ...
  return (
    <section className={`${styles.section} ${styles.sectionGradient}}`}>
       ...
    </section>
  )
}
