Change border colors of TinyMCE on focus and blur


Understanding the Problem

TinyMCE is a popular rich text editor used in various web applications to provide users with a powerful editing experience. One common requirement in user interface design is to enhance the visual feedback of input elements, including editors like TinyMCE. Specifically, when a user focuses on the editor, it can be beneficial to change the border color to indicate that the editor is active. Conversely, when the editor loses focus, the border color can revert to its original state. This article will guide you through the process of achieving this effect, improving user experience and providing clear visual cues.

Scenario Overview

Imagine a web application that uses TinyMCE for content creation. The editor currently has a default appearance, which does not indicate when a user is interacting with it. By modifying the CSS styles to change the border color on focus and blur, you can make the interface more intuitive and user-friendly.

Original Code

The default TinyMCE setup typically looks like this in HTML:

<textarea id="mytextarea">Hello, World!</textarea>
<script src="https://cdn.tiny.cloud/1/no-api-key/tinymce/5/tinymce.min.js" referrerpolicy="origin"></script>
<script>
  tinymce.init({
    selector: '#mytextarea'
  });
</script>

In this setup, there are no additional styles applied to change the border color based on the focus state.

Enhancing User Experience: Custom CSS and JavaScript

To change the border color of the TinyMCE editor on focus and blur, we will need to add custom CSS and JavaScript. This approach provides clear visual feedback when users interact with the editor.

Step-by-Step Implementation

  1. Add Custom CSS: First, define the CSS styles for focus and blur states:
/* Default style for the TinyMCE editor */
.tox-tinymce {
    border: 2px solid #ccc; /* Default border color */
    transition: border-color 0.3s ease; /* Smooth transition */
}

/* Focused style */
.tox-tinymce:focus {
    border-color: #007bff; /* Border color when focused */
}

/* Blur style */
.tox-tinymce:not(:focus) {
    border-color: #ccc; /* Border color when not focused */
}
  1. Modify the TinyMCE Initialization: Next, we can hook into the editor's events to apply our styles dynamically:
tinymce.init({
  selector: '#mytextarea',
  setup: function(editor) {
    editor.on('focus', function() {
      editor.getDoc().body.style.borderColor = '#007bff'; // Change border color on focus
    });
    editor.on('blur', function() {
      editor.getDoc().body.style.borderColor = '#ccc'; // Revert border color on blur
    });
  }
});

Explanation of the Code

  • CSS Styles: The .tox-tinymce class targets the editor's container. We set a default border color and specify a transition for smooth color changes.
  • JavaScript Events: The setup function allows us to register events for focus and blur. Upon focusing the editor, the border color changes to a blue hue, indicating the editor is active. When the editor loses focus, the border color returns to grey.

Additional Insights

  • Accessibility: Providing clear visual feedback is not only a design enhancement but also improves accessibility. Users with cognitive disabilities benefit from clear indicators of which part of the interface is active.
  • Responsive Design: Ensure your CSS changes are responsive. Test the interface on various devices and screen sizes to maintain a good user experience.
  • Customization: You can further customize the colors and styles to match your application's branding, ensuring consistency in the user interface.

Conclusion

Changing the border color of TinyMCE on focus and blur is a simple yet effective way to improve user interaction with the editor. By applying custom CSS and JavaScript events, you create a more engaging experience, guiding users through their content creation journey. Remember to test thoroughly across devices to ensure your changes look and feel right.
