Bootstrap 4 Badges: Enhancing Your Website’s Visual Appeal


In today’s digital age, creating visually appealing and interactive websites has become crucial for businesses to engage and attract their target audience. Bootstrap, a popular front-end framework, offers a wide range of tools and components to enhance the aesthetics and functionality of websites. One such component is Bootstrap 4 badges. In this article, we will explore the various features and applications of Bootstrap 4 badges, and how they can be used to add visual appeal and enhance user experience on your website.

What are Bootstrap 4 badges?

Bootstrap 4 badges are small visual elements used to highlight specific information or provide visual indicators on a website. They can be applied to various HTML elements such as buttons, links, or text to draw attention to specific content. Badges typically consist of a colored background and text, often represented as a small circle or rectangular shape.

Using Bootstrap 4 badges

Applying badges to elements

Adding badges to your website is incredibly easy with Bootstrap 4. By using the <span> element with the class “badge,” you can quickly create a badge and apply it to any HTML element. For example:

<button type="button" class="btn btn-primary">
  Notifications <span class="badge badge-danger">3</span>

In the above code snippet, the badge is added to a button element to display the number of notifications.

Customizing badge styles

Bootstrap 4 provides various contextual classes to customize the appearance of badges. These classes allow you to change the background color, text color, and other visual aspects of the badge. For instance:

<span class="badge badge-primary">New</span>
<span class="badge badge-success">Completed</span>
<span class="badge badge-warning">Pending</span>

By applying different contextual classes, you can match the badge styles to your website’s color scheme and branding.

Adding badge counters

Badge counters are useful for displaying dynamic content, such as the number of unread messages or pending tasks. Bootstrap 4 badges can be easily combined with JavaScript or server-side logic to update the badge count dynamically. For instance:

<a href="/inbox">
  Messages <span class="badge badge-danger" id="unread-count">5</span>

By manipulating the id="unread-count" element using JavaScript, you can update the badge count in real-time.

Bootstrap 4 badge variants

Default badges

Bootstrap 4 provides a default badge style that can be used without any additional classes. The default badge has a gray background and white text color, making it suitable for generic use cases.

Primary, secondary, and other contextual badges

To add more visual impact to your badges, Bootstrap 4 offers contextual classes. These classes allow you to create badges with different background colors based on the purpose or significance of the information. The available contextual classes include primary, secondary, success, danger, warning, info, and light. For example:

<span class="badge badge-primary">Primary</span>
<span class="badge badge-success">Success</span>
<span class="badge badge-danger">Danger</span>

You can choose the appropriate contextual class to align the badge with the intent of the information it represents.

Pill badges

In addition to the default and contextual badges, Bootstrap 4 also offers the option to create pill-shaped badges. Pill badges have rounded corners, providing a visually distinct style compared to the regular badges. To create a pill badge, add the class “badge-pill” to the badge element. For example:

<span class="badge badge-pill badge-info">Info</span>
<span class="badge badge-pill badge-warning">Warning</span>

The “badge-pill” class adds rounded corners to the badge, creating a pill-like shape.

Badge sizes and shapes

Small and large badges

Bootstrap 4 allows you to adjust the size of badges to suit your design requirements. By using additional classes such as “badge-sm” or “badge-lg,” you can create small or large badges, respectively. For instance:

<span class="badge badge-sm badge-primary">Small Badge</span>
<span class="badge badge-lg badge-success">Large Badge</span>

By selecting the appropriate size for your badges, you can ensure they are visually proportional to the surrounding elements.

Rounded badges

To further customize the shape of your badges, Bootstrap 4 offers a “badge-rounded” class. This class adds rounded corners to the badges, giving them a softer and more visually appealing appearance. For example:

<span class="badge badge-primary badge-rounded">Rounded Badge</span>

The “badge-rounded” class enhances the aesthetics of the badge, making it visually distinctive.

Incorporating badges in navigation

Bootstrap 4 badges can also be integrated into navigation menus to provide additional information or highlight active sections. By adding badges to menu items, you can draw attention to specific pages or indicate the presence of new content. For example:

<ul class="nav">
  <li class="nav-item">
    <a class="nav-link" href="#">Home</a>
  <li class="nav-item">
    <a class="nav-link" href="#">Messages
      <span class="badge badge-danger">5</span>
  <li class="nav-item">
    <a class="nav-link" href="#">Profile</a>

In the above code snippet, a badge is added to the “Messages” menu item, indicating the number of unread messages.

Badge positioning and alignment

By default, Bootstrap 4 badges align to the top-right corner of the parent element. However, you can easily modify the positioning using CSS or Bootstrap’s predefined classes. For example, the “badge-top” class aligns the badge to the top-left corner, while the “badge-bottom” class aligns it to the bottom-right corner. You can also use the “position-absolute” class to precisely position the badge within the parent


Using badges for notifications and alerts

Bootstrap 4 badges are an excellent choice for displaying notifications and alerts on your website. By combining badges with JavaScript or AJAX requests, you can create dynamic notifications that update in real-time. For example, you can use badges to show the number of new messages, pending friend requests, or unseen notifications.

Accessibility considerations with Bootstrap 4 badges

When using Bootstrap 4 badges, it is essential to ensure accessibility for all users, including those with disabilities. To make badges accessible, use proper semantic markup and provide alternative text for screen readers. Additionally, ensure that the color contrast between the badge background and text is sufficient for visually impaired users.

Best practices for using Bootstrap 4 badges

To make the most of Bootstrap 4 badges, consider the following best practices:

  1. Use badges sparingly: Avoid overusing badges, as they can overwhelm the user and detract from the overall user experience.
  2. Maintain consistency: Stick to a consistent design style and color scheme for badges throughout your website to create a cohesive visual experience.
  3. Test across devices: Ensure that badges are displayed correctly and maintain their visual appeal on different screen sizes and devices.
  4. Optimize performance: Minimize the use of badges that require frequent updates or server-side calls to avoid performance issues.

Enhancing badges with additional CSS

While Bootstrap 4 badges provide a wide range of customization options, you can further enhance their appearance by applying additional CSS. By leveraging CSS properties such as gradients, box shadows, and animations, you can create unique and eye-catching badges that align with your website’s design theme.
