tailwindcss-mso

A Tailwind CSS plugin that generates MSO utilities.

Useful when styling HTML emails with Tailwind CSS, like in Maizzle.

Installation

npm i tailwindcss-mso

Usage

In your tailwind.config.js:

module.exports = {
  plugins: [
    require('tailwindcss-mso'),
  ],
}

You can now use the classes in your HTML:

<p class="mso-line-height-rule-exactly">...</p>

Options

You may pass options to configure how the plugin generates utilities.

respectImportant

Type: Boolean
Default: false

By default, the plugin does not respect the important option from your Tailwind config, as this may cause issues in Outlook when CSS is inlined.

You may force it to generate !important utilities by setting this to true:

module.exports = {
  plugins: [
    require('tailwindcss-mso')({
      respectImportant: true,
    }),
  ],
}

Result:

<p class="mso-hide-all">...</p>

.mso-hide-all {
  mso-hide: all !important;
}

Arbitrary values

The plugin supports arbitrary values:

<p class="mso-text-raise-[20px]">...</p>

.mso-text-raise-\[20px\] {
  mso-text-raise: 20px;
}

Negative values

Negative values are also supported, just as you'd expect:

<p class="-mso-text-raise-4">...</p>

.-mso-text-raise-4 {
  mso-text-raise: -16px;
}

Generated utilities

The plugin generates both utilities that have default values, as well as utilities based on your Tailwind CSS configuration.

Spacing utilities

These utilities also work with values from your theme.spacing scale:

• mso-line-height-alt
• mso-text-indent-alt
• mso-padding-alt (+ variations)
• mso-margin-alt (+ variations)
• mso-para-margin (+ variations)
• mso-text-raise
• mso-font-width
• mso-element-top, mso-element-left
• mso-ansi-font-size, mso-bidi-font-size
• mso-ansi-font-size, mso-bidi-font-size
• mso-element-frame-width, mso-element-frame-height
• mso-element-frame-vspace, mso-element-frame-hspace
• mso-table-tspace, mso-table-rspace, mso-table-bspace, mso-table-lspace

Where it makes sense, these also support negative versions, like -mso-text-raise-20.
