Buttons

Use Bootstrap’s custom button styles for actions in forms, dialogs, and more with support for multiple sizes, states, and more.

Buttons

<button type="button" class="btn btn-primary">Primary</button>
<button type="button" class="btn btn-secondary">Secondary</button>
<button type="button" class="btn btn-success">Success</button>
<button type="button" class="btn btn-danger">Danger</button>
<button type="button" class="btn btn-warning">Warning</button>
<button type="button" class="btn btn-info">Info</button>
<button type="button" class="btn btn-light">Light</button>
<button type="button" class="btn btn-dark">Dark</button>
<button type="button" class="btn btn-link">Link</button>

Button Tag

The .btn classes are designed to be used with the <button> element. However, you can also use these classes on <a> or <input> elements (though some browsers may apply a slightly different rendering).

Link 
<a class="btn btn-primary" href="#" role="button">Link</a>
<button class="btn btn-primary" type="submit">Button</button>
<input class="btn btn-primary" type="button" value="Input">
<input class="btn btn-primary" type="submit" value="Submit">
<input class="btn btn-primary" type="reset" value="Reset">

Outline buttons

In need of a button, but not the hefty background colors they bring? Replace the default modifier classes with the .btn-outline-* ones to remove all background images and colors on any button. 

<button type="button" class="btn btn-outline-primary">Primary</button>
<button type="button" class="btn btn-outline-secondary">Secondary</button>
<button type="button" class="btn btn-outline-success">Success</button>
<button type="button" class="btn btn-outline-danger">Danger</button>
<button type="button" class="btn btn-outline-warning">Warning</button>
<button type="button" class="btn btn-outline-info">Info</button>
<button type="button" class="btn btn-outline-light">Light</button>
<button type="button" class="btn btn-outline-dark">Dark</button>

Soft buttons

In need of a button, Replace the default modifier classes with the .btn-primary-soft* . 

<button type="button" class="btn btn-primary-soft">Primary soft</button>
<button type="button" class="btn btn-secondary-soft">Secondary soft</button>
<button type="button" class="btn btn-success-soft">Success soft</button>
<button type="button" class="btn btn-danger-soft">Danger soft</button>
<button type="button" class="btn btn-warning-soft">Warning soft</button>
<button type="button" class="btn btn-info-soft">Info soft</button>
<button type="button" class="btn btn-light-soft">Light soft</button>
<button type="button" class="btn btn-dark-soft">Dark soft</button>

Sizes

Fancy larger or smaller buttons? Add .btn-lg or .btn-sm for additional sizes. 

<button type="button" class="btn btn-primary btn-lg">Large button</button>
<button type="button" class="btn btn-secondary btn-lg">Large button</button>
<button type="button" class="btn btn-primary btn-sm">Small button</button>
<button type="button" class="btn btn-secondary btn-sm">Small button</button>

Active state

Buttons will appear pressed (with a darker background, darker border, and inset shadow) when active. There’s no need to add a class to <button> s as they use a pseudo-class . However, you can still force the same active appearance with .active (and include the aria-pressed="true" attribute) should you need to replicate the state programmatically. 

<a href="#" class="btn btn-primary btn-lg active" role="button" aria-pressed="true">Primary link</a>
<a href="#" class="btn btn-secondary btn-lg active" role="button" aria-pressed="true">Link</a>

Disabled state

Make buttons look inactive by adding the disabled boolean attribute to any <button> element. 

<button type="button" class="btn btn-lg btn-primary" disabled>Primary button</button>
<button type="button" class="btn btn-secondary btn-lg" disabled>Button</button>

Block buttons

Create responsive stacks of full-width, “block buttons” like those in Bootstrap 4 with a mix of our display and gap utilities. By using utilities instead of button specific classes, we have much greater control over spacing, alignment, and responsive behaviors. 

<div class="d-grid gap-2">
                                                            <button class="btn btn-primary" type="button">Button</button>
                                                            <button class="btn btn-primary" type="button">Button</button>
                                                          </div>

Here we create a responsive variation, starting with vertically stacked buttons until the md breakpoint, where .d-md-block replaces the .d-grid class, thus nullifying the gap-2 utility. Resize your browser to see them change. 

<div class="d-grid gap-2 d-md-block">
                                                            <button class="btn btn-primary" type="button">Button</button>
                                                            <button class="btn btn-primary" type="button">Button</button>
                                                          </div>

You can adjust the width of your block buttons with grid column width classes. For example, for a half-width “block button”, use .col-6 . Center it horizontally with .mx-auto , too. 

<div class="d-grid gap-2 col-6 mx-auto">
                                                            <button class="btn btn-primary" type="button">Button</button>
                                                            <button class="btn btn-primary" type="button">Button</button>
                                                          </div>

Additional utilities can be used to adjust the alignment of buttons when horizontal. Here we’ve taken our previous responsive example and added some flex utilities and a margin utility on the button to right align the buttons when they’re no longer stacked. 

<div class="d-grid gap-2 d-md-flex justify-content-md-end">
                                                            <button class="btn btn-primary" type="button">Button</button>
                                                            <button class="btn btn-primary" type="button">Button</button>
                                                          </div>

Toggle states

Add data-bs-toggle="button" to toggle a button’s active state. If you’re pre-toggling a button, you must manually add the .active class and aria-pressed="true" to the <button> . 

<button type="button" class="btn btn-primary" data-bs-toggle="button" aria-pressed="false" ="off">
  Single toggle
</button>
