Estilo e Layout

tip

This section is focused on styling through stylesheets. For more advanced customizations (DOM structure, React code...), refer to the swizzling guide.

Um site Docusaurus é uma aplicação React de uma única página. Você pode estilizá-lo da mesma forma que estiliza os aplicativos React.

Há algumas abordagens/frameworks que funcionarão, dependendo das suas preferências e do tipo de site que você está tentando construir. Websites that are highly interactive and behave more like web apps will benefit from more modern styling approaches that co-locate styles with the components. Estilo de componente também pode ser particularmente útil quando você deseja personalizar ou deslizar um componente.

Global styles

This is the most traditional way of styling that most developers (including non-front-end developers) would be familiar with. It works fine for small websites that do not have much customization.

If you're using @docusaurus/preset-classic, you can create your own CSS files (e.g. /src/css/custom.css) and import them globally by passing them as an option of the classic theme.

docusaurus.config.js

module.exports = {
  // ...
  presets: [
    [
      '@docusaurus/preset-classic',
      {
        theme: {
          customCss: [require.resolve('./src/css/custom.css')],
        },
      },
    ],
  ],
};

Qualquer CSS que você escrever nesse arquivo estará disponível globalmente e pode ser referenciado diretamente usando strings literais.

/src/css/custom.css

.purple-text {
  color: rebeccapurple;
}

function MyComponent() {
  return (
    <main>
      <h1 className="purple-text">Purple Heading!</h1>
    </main>
  );
}

If you want to add CSS to any element, you can open the DevTools in your browser to inspect its class names. Class names come in several kinds:

• Theme class names. These class names are listed exhaustively in the next subsection. They don't have any default properties. You should always prioritize targeting those stable class names in your custom CSS.
• Infima class names. These class names are found in the classic theme and usually follow the BEM convention of block__element--modifier. They are usually stable but are still considered implementation details, so you should generally avoid targeting them. However, you can modify Infima CSS variables.
• CSS module class names. These class names have a hash in production (codeBlockContainer_RIuc) and are appended with a long file path in development. They are considered implementation details and you should almost always avoid targeting them in your custom CSS. If you must, you can use an attribute selector ([class*='codeBlockContainer']) that ignores the hash.

Theme Class Names

We provide some stable CSS class names for robust and maintainable global layout styling. These names are theme-agnostic and meant to be targeted by custom CSS.

tip

If you can't find a way to create a robust CSS selector, please report your customization use-case and we will consider adding new class names.

Styling your site with Infima

@docusaurus/preset-classic uses Infima as the underlying styling framework. Infima provides a flexible layout and common UI components styling suitable for content-centric websites (blogs, documentation, landing pages). For more details, check out the Infima website.

When you scaffold your Docusaurus project with create-docusaurus, the website will be generated with basic Infima stylesheets and default styling. You can override Infima CSS variables globally.

/src/css/custom.css

:root {
  --ifm-color-primary: #25c2a0;
  --ifm-code-font-size: 95%;
}

Infima usa 7 tonalidades de cada cor. We recommend using ColorBox to find the different shades of colors for your chosen primary color.

Alternatively, use the following tool to generate the different shades for your website and copy the variables into /src/css/custom.css.

tip

Aim for at least WCAG-AA contrast ratio for the primary color to ensure readability. Use the Docusaurus website itself to preview how your color palette would look like. You can use alternative palettes in dark mode because one color doesn't usually work in both light and dark mode.

Primary Color:

Background:

CSS Variable Name	Hex	Adjustment	Contrast Rating
--ifm-color-primary-lightest	#3cad6e		Fail 🔴
--ifm-color-primary-lighter	#359962		Fail 🔴
--ifm-color-primary-light	#33925d		Fail 🔴
--ifm-color-primary	#2e8555	0	AA 👍
--ifm-color-primary-dark	#29784c		AA 👍
--ifm-color-primary-darker	#277148		AA 👍
--ifm-color-primary-darkest	#205d3b		AAA 🏅

Replace the variables in src/css/custom.css with these new variables.

/src/css/custom.css

:root {
  --ifm-color-primary: #2e8555;
  --ifm-color-primary-dark: #29784c;
  --ifm-color-primary-darker: #277148;
  --ifm-color-primary-darkest: #205d3b;
  --ifm-color-primary-light: #33925d;
  --ifm-color-primary-lighter: #359962;
  --ifm-color-primary-lightest: #3cad6e;
}

Dark Mode

In light mode, the <html> element has a data-theme="light" attribute; in dark mode, it's data-theme="dark". Therefore, you can scope your CSS to dark-mode-only by targeting html with a specific attribute.

/* Overriding root Infima variables */
[data-theme='dark'] {
  --ifm-color-primary: #4e89e8;
}
/* Styling one class specially in dark mode */
[data-theme='dark'] .purple-text {
  color: plum;
}

tip

It is possible to initialize the Docusaurus theme directly from a docusaurus-theme query string parameter.

Examples:

• https://docusaurus.io/?docusaurus-theme=dark
• https://docusaurus.io/docs/configuration?docusaurus-theme=light

Mobile View

Docusaurus uses 996px as the cutoff between mobile screen width and desktop. If you want your layout to be different in the mobile view, you can use media queries.

.banner {
  padding: 4rem;
}
/** In mobile view, reduce the padding */
@media screen and (max-width: 996px) {
  .heroBanner {
    padding: 2rem;
  }
}

CSS modules

To style your components using CSS Modules, name your stylesheet files with the .module.css suffix (e.g. welcome.module.css). Webpack will load such CSS files as CSS modules and you have to reference the class names as properties of the imported CSS module (as opposed to using plain strings). This is similar to the convention used in Create React App.

styles.module.css

.main {
  padding: 12px;
}

.heading {
  font-weight: bold;
}

.contents {
  color: #ccc;
}

import styles from './styles.module.css';

function MyComponent() {
  return (
    <main className={styles.main}>
      <h1 className={styles.heading}>Hello!</h1>
      <article className={styles.contents}>Lorem Ipsum</article>
    </main>
  );
}

The class names will be processed by webpack into a globally unique class name during build.

CSS-in-JS

warning

CSS-in-JS support is a work in progress, so libs like MUI may have display quirks. Welcoming PRs.

Sass/SCSS

To use Sass/SCSS as your CSS preprocessor, install the unofficial Docusaurus 2 plugin docusaurus-plugin-sass. Este plug-in funciona tanto para estilos globais quanto para a abordagem de módulos CSS:

1. Install docusaurus-plugin-sass:

npm

npm install --save docusaurus-plugin-sass sass

Yarn

yarn add docusaurus-plugin-sass sass

pnpm

pnpm add docusaurus-plugin-sass sass

2. Include the plugin in your docusaurus.config.js file:

docusaurus.config.js

module.exports = {
  // ...
  plugins: ['docusaurus-plugin-sass'],
  // ...
};

3. Escreva e importe suas folhas de estilo no Sass/SCSS normalmente.

Global styles using Sass/SCSS

You can now set the customCss property of @docusaurus/preset-classic to point to your Sass/SCSS file:

docusaurus.config.js

module.exports = {
  presets: [
    [
      '@docusaurus/preset-classic',
      {
        // ...
        theme: {
          customCss: [require.resolve('./src/css/custom.scss')],
        },
        // ...
      },
    ],
  ],
};

Modules using Sass/SCSS

Name your stylesheet files with the .module.scss suffix (e.g. welcome.module.scss) instead of .css. Webpack will use sass-loader to preprocess your stylesheets and load them as CSS modules.

styles.module.scss

.main {
  padding: 12px;

  article {
    color: #ccc;
  }
}

import styles from './styles.module.scss';

function MyComponent() {
  return (
    <main className={styles.main}>
      <article>Lorem Ipsum</article>
    </main>
  );
}
