I've found myself feeling limited by the styles provided by the framework so I looked into what it takes to use a stylesheet.

A bit of searching around ended up pointing me towards this Github issue which helps a user integrate Tailwindcss, a framework I've been using professionally and in personal projects for awhile now.

According to the responses within the issue, there are two ways of bringing in TailwindCSS:

1. Import TailwindCSS through their CDN:

Edit your config file at .vitepress/config.js and add the following.

module.exports = {
    head: [
        ['link', { rel: 'stylesheet', href: 'https://unpkg.com/tailwindcss@2.0.4/dist/tailwind.min.css' }]
    ]
};

This is quick and easy, but you miss out on some of the key TailwindCSS features as stated on their site:

Before using the CDN build, please note that many of the features that make Tailwind CSS great are not available without incorporating Tailwind into your build process.

• You can't customize Tailwind's default theme
• You can't use any directives like @apply, @variants, etc
• You can't enable additional variants like group-focus
• You can't install third-party plugins
• You can't tree-shake unused styles

2. Download using npm/yarn:

Github user ky-is posted an answer linking to this repo that is a blank Vitepress project with TailwindCSS working.

The first step is to update your package.json's so that it at least has:

{
    ...,
    "devDependencies": {
      "@tailwindcss/postcss7-compat": "^2.0.4",
      "autoprefixer": "^9",
      "postcss": "^7",
      "vitepress": "^0.12.2"
  },
  "postcss": {
    "plugins": {
      "tailwindcss": {},
      "autoprefixer": {}
    }
  }
}

Make sure to run yarn install or npm install after updating your package.json file to update your dependencies.

Please note the comment by user neilmispelaar within the issue thread posted above:

At time of writing, somewhere in the project dependencies postCSS version 7 is being referenced, but TailwindCSS uses PostCSS version 8. This is why in your package.json you have to reference a version of TailwindCSS that is compatible with PostCSS version 7. Fun Bonus: If you use this compatible version of TailwindCSS then you can not use AutoPrefixer past version 9.

It may also be worth going over https://tailwindcss.com/docs/installation#post-css-7-compatibility-build if you run into issues.

The next key step is adding the theme folder within your .vitepress directory.

Create an index.js file with the following:

import './tailwind.postcss'

import DefaultTheme from 'vitepress/dist/client/theme-default'
export default { ...DefaultTheme }

and a tailwind.postcss file with the following:

@tailwind base;

@tailwind components;

@tailwind utilities;

The last step is to create a tailwind.config.js file within your root directory and update the purgecss settings:

module.exports = {
  purge: {
    enabled: process.env.NODE_ENV === 'production',
    content: [
      './docs/.vitepress/**/*.js',
      './docs/.vitepress/**/*.vue',
      './docs/.vitepress/**/*.ts',
    ],
    options: {
      safelist: ['html', 'body'],
    },
  },
}

Congratulations! TailwindCSS should now be usable within your .md files.

Example:

Here is an example of this article using TailwindCSS alongside Vitepress' built in markdown formatting:

# Configuring TailwindCSS to work with Vitepress

<div class="flex flex-col items-center mt-10 sm:flex-row">
  <img src="../images/vite-logo.svg" alt="Vite package logo" width="200" height="200" style="float: left; margin-right: 12px;" />
  <p class="italic text-gray-500">
