Selectors

Responsive prefixes

Most classes you will encounter can be used with responsive prefixes. This gives you the option to use classes according to the screen size.

Example

<p class="fs-12 sm:fs-13 md:fs-14 lg:fs-16 xl:fs-18">
  Lorem ipsum dolor sit amet, consectetur adipisicing elit.
</p>

sm:	Small	390px
md:	Medium	768px
lg:	Large	1024px
xl:	Extra large	1400px

Containers

Containers are used to limit the width of content, preventing content from overflowing beyond the specified size.

Example

<div class="container-xl">content</div>

Production build

We strongly recommend to use postcss with autoprefixer and postcss-purgecss. This stack will extend the CSS rules with browser specific prefixes, like -webkit and will remove unused styles in production build.

npm i -D postcss autoprefixer @fullhuman/postcss-purgecss

Our postcss.config.js config. You need to configure the content parameter for your project.

module.exports = {
  plugins:
    process.env.NODE_ENV === 'production'
      ? [
          'autoprefixer',
          [
            '@fullhuman/postcss-purgecss',
            {
              content: ['./{pages,components}/**/*.{js,jsx}'],
              safelist: ['html', 'body'],
              defaultExtractor: (content) => content.match(/[\w-/:]+(?<!:)/g) || [],
            },
          ],
        ]
      : ['autoprefixer'],
};
