Welcome to The Coding College! In this article, we’ll explore Bootstrap 5 Tooltips, an effective way to provide additional context and information to users without cluttering your website’s interface.

Getting Started with Bootstrap 5 Tooltips

1. Include Bootstrap

To use tooltips, ensure Bootstrap 5’s CSS and JavaScript are included in your project. Use the CDN for quick integration:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Bootstrap 5 Tooltip Example</title>
  <link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
  <script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.bundle.min.js"></script>
</body>
</html>

Basic Tooltip Implementation

Here’s how to add a tooltip to an element:

<button type="button" class="btn btn-secondary" data-bs-toggle="tooltip" data-bs-placement="top" title="This is a tooltip!">
  Hover over me
</button>

Breaking Down the Code

  1. data-bs-toggle="tooltip"
    This attribute activates the tooltip feature.
  2. data-bs-placement="top"
    Specifies the position of the tooltip (top, bottom, left, or right).
  3. title="This is a tooltip!"
    The title attribute defines the content of the tooltip.

Initializing Tooltips

To activate tooltips on your page, you must initialize them using Bootstrap’s JavaScript. Add the following script to your HTML file:

document.addEventListener('DOMContentLoaded', function () {
  var tooltipTriggerList = [].slice.call(document.querySelectorAll('[data-bs-toggle="tooltip"]'));
  var tooltipList = tooltipTriggerList.map(function (tooltipTriggerEl) {
    return new bootstrap.Tooltip(tooltipTriggerEl);
  });
});

This script initializes all elements with the data-bs-toggle="tooltip" attribute.

Customizing Tooltips

1. Tooltip Placement

You can place tooltips in different positions using the data-bs-placement attribute. Available options include:

  • top
  • bottom
  • left
  • right
  • auto (automatically adjusts based on space)

Example:

<button type="button" class="btn btn-secondary" data-bs-toggle="tooltip" data-bs-placement="bottom" title="Tooltip on the bottom">
  Bottom Tooltip
</button>

2. Tooltip Trigger Options

By default, tooltips are triggered on hover and focus. You can customize this behavior using the data-bs-trigger attribute:

  • hover
  • focus
  • click
  • manual

Example:

<button type="button" class="btn btn-secondary" data-bs-toggle="tooltip" data-bs-trigger="click" title="Click to see this tooltip">
  Click Tooltip
</button>

3. Adding HTML Content

Bootstrap 5 allows HTML content inside tooltips. Enable this feature using the data-bs-html="true" attribute:

<button type="button" class="btn btn-secondary" data-bs-toggle="tooltip" data-bs-html="true" title="<b>Bold Text</b> and <i>Italic Text</i>">
  HTML Tooltip
</button>

4. Delay Tooltips

You can delay the appearance and hiding of tooltips using the delay option in JavaScript:

var tooltip = new bootstrap.Tooltip(document.querySelector('.btn'), {
  delay: { show: 500, hide: 200 }
});

This code delays the tooltip’s appearance by 500ms and hides it after 200ms.

5. Custom Styling

To customize the tooltip’s appearance, override its CSS classes. For example:

.tooltip-inner {
  background-color: #4CAF50; /* Green background */
  color: #fff; /* White text */
  font-size: 14px;
}

.tooltip-arrow {
  border-color: #4CAF50; /* Arrow color */
}

Accessibility Features

Bootstrap 5 Tooltips are designed with accessibility in mind:

  • Keyboard Navigation: Users can focus on elements to trigger tooltips.
  • Screen Readers: Use ARIA attributes like aria-describedby to provide context.

Example:

<button type="button" class="btn btn-secondary" data-bs-toggle="tooltip" data-bs-placement="top" title="Accessible tooltip">
  Accessible Tooltip
</button>

FAQs About Bootstrap 5 Tooltips

1. Why isn’t my tooltip working?

Ensure you’ve initialized tooltips with JavaScript. Also, check for missing Bootstrap dependencies.

2. Can tooltips display dynamic content?

Yes! Use JavaScript to update the title attribute or call the setContent method.

3. How do I destroy a tooltip?

Use the dispose method to remove a tooltip instance:

var tooltipInstance = bootstrap.Tooltip.getInstance(document.querySelector('.btn'));
tooltipInstance.dispose();

Conclusion

Bootstrap 5 Tooltips are powerful, lightweight components that improve user experience by providing additional context or information on demand. With simple HTML attributes and a touch of JavaScript, you can create dynamic and accessible tooltips for your website.
