Usage

First create a html file that will be used when creating the html code that will have styles in it.

HTML

You can call a CSS object by using {# and }. Everything between those two is the name of the css object. You can call variables using {$ and }. Everything between those two is the name of the variable.

CSS

Every css object must start with a # (ID selector), for example;

#some-style {
  background: red;
}

Example

<div style="{#container}">
  <div style="{#block}">
    <div style="{#content}">
      <h3 style="{#title}">Verify</h3>
      <p style="{#text}">Thank you for registering to our service, please let us know that this was an intended action by clicking the verify button below. If you didn't register you can ignore this mail.</p>

// Add mail styler.
const MailStyler = require('html-mail-styler')
const ms = new MailStyler()

// Import FileSystem
const fs = require('fs')

// Get CSS and HTML file.
const html = fs.readFileSync(__dirname + '/verification_mail.html').toString()
const css = fs.readFileSync(__dirname + '/styles.css').toString()

// Add css to Mail Styler
ms.addCss(css)

// Add Variables
ms.set('code', 'some-verification-code')

// Get HTML result
const result = ms.html(html)

The above code will look like

Okay, so how does it work?

MailStyler.addCss(string CSS_Code)

Add CSS Code to the parser, called like {#example}

MailStyler.set(string key, string value)

Set variables, called like {$example}

MailStyler.html(string HTML_Code)

Returns the parsed html code.
