What is a WYSIWYG editor? The Working Mechanics of a WYSIWYG Editor

Let’s understand how WYSIWYG editors work.

HTML and CSS: The Building Blocks

WYSIWYG editors structure content with HTML (Hyper Text Markup Language) and style it with CSS (Cascading Style Sheets). They complement each other like peanut butter and jelly. Consider HTML to be the architect of the web world.  Furthermore, it organizes all of the content on web pages. CSS, like a fashion designer, adds pizazz with colors, fonts, and sizes. It’s like having a personal assistant who instantly turns your creative input into HTML with some gorgeous CSS sprinkled on top in a WYSIWYG editor. You don’t have to be a coding genius to make your site content seem amazing!

The Role of the Document Object Model (DOM)

The Document Object Model (DOM) acts as the blueprint of a webpage, structuring every element in a hierarchical order. When you use a WYSIWYG editor, you’re interacting with the DOM in real time. Each change you make—whether adding text, inserting images, or adjusting styles—gets instantly reflected in the preview.

Think of the DOM as a conductor leading an orchestra, ensuring all elements work in harmony. Your WYSIWYG editor seamlessly translates your input into HTML elements, giving you instant visual feedback on how your page will look.

JavaScript: Bringing Interactivity to Life

JavaScript is the powerhouse that makes WYSIWYG editors interactive. Every time you apply formatting, resize an image, or adjust a layout, JavaScript dynamically updates the DOM.

It’s like having a smart assistant that listens to your commands and applies them instantly. Whether you’re adjusting text alignment, embedding media, or fine-tuning layouts, JavaScript ensures the editor responds smoothly, giving you a real-time, code-free editing experience.

The Magic Behind WYSIWYG Editors

Now that you know the essentials—HTML, CSS, DOM, and JavaScript—you can see how WYSIWYG editors simplify web design. They transform complex coding into an intuitive visual experience, allowing you to create beautiful web pages effortlessly.

Essential Features of WYSIWYG Editors

A WYSIWYG editor isn’t just about writing text—it’s a powerful tool designed to streamline web content creation. Whether you’re a developer or a content creator, these editors offer intuitive features that make designing and formatting web pages a breeze. Let’s explore the key functionalities that set WYSIWYG editors apart.

1. Rich Text Editing and Formatting

The core of every WYSIWYG editor is the ability to format text effortlessly. You can:

• Apply bold, italics, underline, and strikethrough
• Adjust font styles, sizes, and colors
• Create structured content with headings (H1-H6)
• Align text left, center, right, or justify

With these options, you can style content just as you would in a word processor—without touching any code.

2. Drag-and-Drop Functionality

Modern WYSIWYG editors allow you to drag and drop elements onto the page effortlessly. Whether you’re adding images, buttons, or sections, the editor visually updates in real time, letting you see changes as they happen.

3. Image and Media Embedding

Need to add visuals? WYSIWYG editors let you:

• Upload and insert images (JPG, PNG, GIF)
• Embed videos from platforms like YouTube and Vimeo
• Add audio files for podcasts or music

Some editors even provide image editing tools, allowing you to crop, resize, or apply filters directly.

4. Tables, Lists, and Special Elements

Structuring content is easy with built-in tools for:

How WYSIWYG Editors Work Behind the Scenes

Client and Server-side Rendering

WYSIWYG editors mostly rely on client-side rendering, in which your web browser generates the HTML document. Some editors, however, prefer server-side rendering for specialized purposes such as previewing or rendering saved content. The rendering style selected can have a significant impact on performance and user experience. It’s like choosing between a fast sports car or a relaxing cruise.

APIs and Data Exchange

The unsung heroes of real-time editing are APIs (Application Programming Interfaces). They improve communication between editor elements and even allow interaction with other systems. APIs provide smooth data communication, making your editing experience a snap, from saving drafts to collaborating with others.

How to Integrate WYSIWYG Editors with Web Projects

Integrating a WYSIWYG editor into your web project can significantly enhance your content editing experience. One of the most popular editors available is Froala, a lightweight and powerful WYSIWYG editor. In this guide, you’ll learn how to integrate Froala into an HTML, CSS, and JavaScript project with a simple setup.

Step 1: Include Froala’s CSS and JavaScript Files

To use Froala, you need to include its required CSS and JS files in your project. You can either download these files or use a CDN (Content Delivery Network) for easier integration.

Add the following lines inside the <head> section of your HTML file:

<!-- Froala Editor CSS -->
<link href='https://cdn.jsdelivr.net/npm/froala-editor@latest/css/froala_editor.pkgd.min.css' rel='stylesheet' type='text/css' />

And include the Froala JavaScript file before the closing </body> tag:

<!-- Froala Editor JS -->
<script type='text/javascript' src='https://cdn.jsdelivr.net/npm/froala-editor@latest/js/froala_editor.pkgd.min.js'></script>

Step 2: Create DOM Element

The Froala Editor is quite flexible and you can initialize it to ‘attach’ to any standard HTML DOM element, such as a DIV, or a TEXTAREA. In this example I will use a DIV element, as follows:

<div id="example"></div>

The “example” id ties the div element to the instance of the Froala Editor that will be initialized in the following step.

Step 3: Initialize the Editor

Let’s initialize the Froala Editor on our empty element created in the previous step.

var editor = new FroalaEditor('#example');

Full Initialization Code Example to Create a Simple HTML Text Editor

Let’s follow all the above steps to create a simple HTML Text Editor.

<!DOCTYPE html>
<html>

    <head>
        <meta charset="utf-8">
        <meta name="viewport" content="width=device-width, height=device-height, initial-scale=1.0, maximum-scale=1.0" />
        <link href='https://cdn.jsdelivr.net/npm/froala-editor@latest/css/froala_editor.pkgd.min.css' rel='stylesheet' type='text/css' />
    </head>

    <body>

        <div id="example"></div>

        <script type='text/javascript' src='https://cdn.jsdelivr.net/npm/froala-editor@latest/js/froala_editor.pkgd.min.js'></script>  
        <script> 
            var editor = new FroalaEditor('#example');
        </script>
    </body>

</html>

Here is the output:

Customizing Your WYSIWYG Editor

Froala allows you to customize toolbars, styles, and plugins. Below is an example of enabling only specific features like bold, italic, and underline:

var editor = new FroalaEditor('#example', {
    toolbarButtons: ['bold', 'italic', 'underline'],
    heightMin: 200,
    heightMax: 400
});

You can add more customizations like uploading images, adding tables, or integrating with a database.

Save the Editor’s Content

To retrieve and save the content written in the WYSIWYG editor, you can use JavaScript to extract the HTML content:

document.querySelector("#saveBtn").addEventListener("click", function() {
    let editorContent = document.querySelector(".fr-element").innerHTML;
    console.log("Saved Content:", editorContent);
});

This content can then be stored in a database or sent to a server using an AJAX request.

Here’s the updated code with the save button functionality added:

<!DOCTYPE html>
<html>

<head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, height=device-height, initial-scale=1.0, maximum-scale=1.0" />
    <link href='https://cdn.jsdelivr.net/npm/froala-editor@latest/css/froala_editor.pkgd.min.css' rel='stylesheet' type='text/css' />
    <title>Froala WYSIWYG Editor Example</title>
</head>

<body>

    <h2>Froala WYSIWYG Editor</h2>

    <!-- Editor Container -->
    <div id="example"></div>

    <!-- Save Button -->
    <button id="saveBtn">Save Content</button>

    <!-- Froala JS -->
    <script type='text/javascript' src='https://cdn.jsdelivr.net/npm/froala-editor@latest/js/froala_editor.pkgd.min.js'></script>  
    <script> 
        // Initialize Froala Editor
        var editor = new FroalaEditor('#example');

        // Save Button Functionality
        document.querySelector("#saveBtn").addEventListener("click", function() {
            let editorContent = document.querySelector(".fr-element").innerHTML;
            console.log("Saved Content:", editorContent);
            alert("Content Saved! Check the console for output.");
        });
    </script>

</body>

</html>

Your output will look like this:
