Add attributes

Maizzle can automatically add attributes to HTML elements in your email templates.

This can be useful for:

• adding default attributes based on build Environment or Template
• not having to write required attributes all the time
• automating email accessibility

The extraAttributes key in your config defines which elements in your emails should receive which attributes with what values.

Usage

Here is how you would add a role="article" attribute to a <div>:

module.exports = {
  extraAttributes: {
    div: {
      role: 'article'
    }
  }
}

Default attributes

By default, Maizzle makes any <table> accessible, resets its spacing, and ensures that an empty alt="" attribute is added to images that don't have it.

This is the default configuration:

let attributes = {
  table: {
    cellpadding: 0,
    cellspacing: 0,
    role: 'none'
  },
  img: {
    alt: ''
  }
}

Disabling

You may turn this off by setting extraAttributes to false in your config:

module.exports = {
  extraAttributes: false,
}

Selectors

Tag, class, id, and attribute selectors are supported:

module.exports = {
  extraAttributes: {
    div: {
      id: 'new'
    },
    '.test': {
      editable: true
    },
    '#test': {
      'data-foo': 'bar'
    },
    '[role]': {
      'aria-roledescription': 'slide'
    }
  }
}

Multiple selectors

Add multiple attributes to multiple elements in one go:

module.exports = {
  extraAttributes: {
    'div, p': {
      class: 'test'
    },
    'div[role=alert], section.alert': {
      class: 'alert'
    }
  }
}

Tailwind CSS

Any Tailwind CSS classes that you add with this Transformer need to be added to your content key, otherwise they will not be generated.

To do this, simply add the path to your config.js file to the content array:

module.exports = {
  content: ['./config.js'],
}

API

const {applyExtraAttributes} = require('@maizzle/framework')
const options = {
  div: {
    role: 'article'
  }
}

const html = await applyExtraAttributes('<div></div>', options)
