bootstrap button outline with code examples


Bootstrap is a popular framework for creating responsive and intuitive websites. One of the many components that Bootstrap provides is the button component. Buttons are an essential part of any website as they allow users to interact with the website's functionalities.

Bootstrap's button component offers two types of buttons: filled and outline. In this article, we will discuss Bootstrap's button outline, including its features, syntax, and code examples.

Features of Bootstrap button outline:

The button outline in Bootstrap is a button with an outline rather than a filled color, giving it a border-like appearance. The outline color can be customized to match the website's color scheme, making it an excellent option for designers looking for more control over their website's visuals.

One of the primary advantages of using the button outline is that it offers a more subtle look while still providing a clear call-to-action. It is also useful in cases where a high contrast between the background and button text is not needed, such as when adding a subtle button to a header or footer section.

Syntax for Bootstrap button outline:

The Bootstrap button outline has a similar syntax as other Bootstrap button components. The only difference is that instead of using the "btn-default" class, the "btn-outline-primary" class is used.

Here is an example of the syntax for creating a button outline in Bootstrap:

<button type="button" class="btn btn-outline-primary">Button</button>

This will create a button outline with a blue border and white text, indicating that it is the primary call-to-action button.

Code examples of Bootstrap button outline:

  1. Button outline with primary color:
<button type="button" class="btn btn-outline-primary">Button</button>
  1. Button outline with success color:
<button type="button" class="btn btn-outline-success">Button</button>
  1. Button outline with warning color:
<button type="button" class="btn btn-outline-warning">Button</button>
  1. Button outline with danger color:
<button type="button" class="btn btn-outline-danger">Button</button>
  1. Button outline with custom color:
<button type="button" class="btn btn-outline-custom">Button</button>

In the above example, the "btn-outline-custom" class can be defined in a CSS file to set the button's border color.


Bootstrap's button outline is an excellent option for designers looking to create subtle call-to-action buttons without overwhelming the user with a filled color button. Its customization options make it a versatile component in any web designer's toolkit. With the examples provided above, you should now have a solid understanding of how to use and customize the Bootstrap button outline.

  1. Bootstrap Button Features:

In addition to the outline button, Bootstrap provides many features to customize its button component. Here are some of the features of Bootstrap buttons:

  • Sizes: Bootstrap buttons can be large, small, or extra small, using the "btn-lg", "btn-sm", and "btn-xs" classes, respectively.

  • Disabled: Buttons can be disabled by adding the "disabled" attribute to the button element.

  • Active: Buttons can also be marked as active by using the "active" class.

  • Block level: Buttons can be made full-width using the "btn-block" class.

  1. Bootstrap Button Syntax:

The Bootstrap button component has a straightforward syntax that consists of a button element with a few classes. Here is a basic syntax for a Bootstrap button:

<button type="button" class="btn btn-primary">Button</button>

In this example, we can see that the button element has a type attribute set to "button," which indicates that it's a button and not a submit or reset form button. Additionally, it has two classes, "btn" and "btn-primary," which indicate that it's a button and the primary call-to-action color.

Here are some examples of Bootstrap buttons with different styles, colors, and features:

  • Large primary button:
<button type="button" class="btn btn-primary btn-lg">Learn more</button>
  • Small danger button:
<button type="button" class="btn btn-danger btn-sm">Delete</button>
  • Block level success button:
<button type="button" class="btn btn-success btn-block">Save changes</button>
