Why a Live Preview for HTML Code Writers is Crucial for Users

Providing users with a live preview feature offers several significant benefits:

Instant Learning

Instant feedback allows users to see the HTML code corresponding to their input immediately. This real-time interaction helps users learn HTML as they type, reinforcing the connection between their actions and the resulting code. For instance, when a user types a paragraph, they can instantly see the <p> tags surrounding their text, making the learning process more intuitive and immediate.

Enhanced Engagement

Users are more likely to engage with a tool that provides immediate visual feedback. This engagement can lead to better content creation and a more satisfying user experience, as users can see the effects of their changes instantly. Imagine a user adding a link and immediately seeing the <a> tag in action, making them understand how links are structured in HTML.

Improved Accuracy

By allowing users to see the HTML code behind their text, developers can help them create cleaner, more accurate code. This visibility reduces errors and enhances the overall quality of the content. For example, users can quickly identify and correct issues like unclosed tags or incorrect attributes.

  <textarea id="froala"></textarea>
  <div id="eg-previewer"></div>

  <script src=""></script>

Next, initialize Froala Editor with the Code View plugin enabled. This will allow users to switch between the WYSIWYG editor and the HTML code view.

  var editor = new FroalaEditor('#froala', {
    pluginsEnabled: ['codeView'],
    codeViewKeepActiveButtons: ['selectAll'],
    events: {
      'codeView.update': function () {
        // Update the live preview
        document.getElementById("eg-previewer").textContent = this.codeView.get();
