<!DOCTYPE html>
    <title>Article Editor</title>
    <meta charset="utf-8">

    <!-- css -->
    <link rel="stylesheet" href="/your-article-dist-path/article-editor.min.css" />
    <!-- element -->
    <textarea id="entry">...</textarea>

    <!-- js -->
    <script src="/your-article-dist-path/article-editor.min.js"></script>

    <!-- call -->
    ArticleEditor('#entry', {
        css: '/your-article-dist-path/',
        custom: {
            css: ['/your-article-dist-path/my-custom.css']
        formatAdd: {
            "note": {
                title: '<span style="padding: 6px 8px; background-color: #FEF2C3; color: #645F4A;">Note</span>',
                type: 'paragraph',
                params: {
                    tag: 'p',
                    classname: 'my-note'
            "redheading": {
                title: '<span style="color: #F93943; font-weight: bold; font-size: 16px;">Red Heading</span>',
                type: 'heading',
                params: {
                    tag: 'h2',
                    classname: 'red-heading'


In the example Article gets the styles for formatAdd from the my-custom.css file, this is how it might look like:

// my-custom.css
.my-note {
    background-color: #FEF2C3;
    color: #645F4A;
    padding: 24px 28px;
.red-heading {
    color: #F93943;
