Key Features of Bootstrap 5 Modals

  • Customizable Content: Add images, forms, text, and more.
  • Responsive Design: Adapts to all screen sizes automatically.
  • Keyboard and Focus Management: Improves accessibility for all users.
  • Pre-built Animations: Smooth transitions enhance user experience.

Getting Started with Bootstrap 5 Modals

1. Include Bootstrap

Before using Modals, ensure you’ve included Bootstrap’s CSS and JavaScript files. Use a CDN for quick setup:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Bootstrap 5 Modal 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>

Creating a Basic Modal

Here’s the simplest example of a modal:

<!-- Trigger Button -->
<button type="button" class="btn btn-primary" data-bs-toggle="modal" data-bs-target="#exampleModal">
  Launch Modal
</button>

<!-- Modal Structure -->
<div class="modal fade" id="exampleModal" tabindex="-1" aria-labelledby="exampleModalLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalLabel">Modal Title</h5>
        <button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
      </div>
      <div class="modal-body">
        This is the modal body content.
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" data-bs-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save Changes</button>
      </div>
    </div>
  </div>
</div>

Breaking Down the Code

  • Trigger Button:
    • The button with data-bs-toggle="modal" and data-bs-target="#exampleModal" is used to open the modal.
<button type="button" class="btn btn-primary" data-bs-toggle="modal" data-bs-target="#exampleModal">
  Launch Modal
</button>
  • Modal Wrapper:
    • The modal is defined with the modal class and fade animation.The id must match the data-bs-target attribute of the button.
<div class="modal fade" id="exampleModal" tabindex="-1" aria-labelledby="exampleModalLabel" aria-hidden="true">
  • Modal Content:
    • Comprises three main sections:
      • Header: Includes a title and close button.
      • Body: Displays the main content.
      • Footer: Contains action buttons (e.g., Save or Close).

Advanced Customizations

1. Large and Small Modals

You can resize modals using modal-lg or modal-sm classes in the modal-dialog:

<div class="modal-dialog modal-lg">
  <div class="modal-content">
    <!-- Modal Content -->
  </div>
</div>
<div class="modal-dialog modal-sm">
  <div class="modal-content">
    <!-- Modal Content -->
  </div>
</div>

2. Centering Modals

To vertically and horizontally center the modal, add the modal-dialog-centered class:

<div class="modal-dialog modal-dialog-centered">
  <div class="modal-content">
    <!-- Modal Content -->
  </div>
</div>

3. Static Backdrop

Prevent the modal from closing when clicking outside by adding the data-bs-backdrop="static" attribute:

<div class="modal fade" id="staticBackdrop" data-bs-backdrop="static" data-bs-keyboard="false" tabindex="-1" aria-labelledby="staticBackdropLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <!-- Modal Content -->
    </div>
  </div>
</div>

4. Scrollable Modals

For modals with long content, make the body scrollable by adding modal-dialog-scrollable:

<div class="modal-dialog modal-dialog-scrollable">
  <div class="modal-content">
    <!-- Modal Content -->
  </div>
</div>

5. Add Forms Inside Modals

Modals are perfect for login or signup forms. Here’s an example:

<div class="modal fade" id="formModal" tabindex="-1" aria-labelledby="formModalLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="formModalLabel">Login</h5>
        <button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
      </div>
      <div class="modal-body">
        <form>
          <div class="mb-3">
            <label for="email" class="form-label">Email address</label>
            <input type="email" class="form-control" id="email" placeholder="[email protected]">
          </div>
          <div class="mb-3">
            <label for="password" class="form-label">Password</label>
            <input type="password" class="form-control" id="password">
          </div>
          <button type="submit" class="btn btn-primary">Submit</button>
        </form>
      </div>
    </div>
  </div>
</div>
