Use the button classes on button, a, and input elements.

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


Six different button types are available for most situations.

<button type="button" class="btn btn-default">btn-default</button>
<button type="button" class="btn btn-primary">btn-primary</button>
<button type="button" class="btn btn-danger">btn-danger</button>
<button type="button" class="btn btn-inverse">btn-inverse</button>
<button type="button" class="btn btn-outline">btn-outline</button>
<button type="button" class="btn btn-link">link</button>


Add a .btn-lg, .btn-sm, or .btn-mini class for additional sizing options.

<button type="button" class="btn btn-default btn-lg">btn-lg</button>
<button type="button" class="btn btn-default">default</button>
<button type="button" class="btn btn-default btn-sm">btn-sm</button>
<button type="button" class="btn btn-default btn-mini">btn-mini</button>

Disabled Buttons

Adding the disabled attribute to a button element will disable it.

<button type="button" class="btn btn-default" disabled>btn-default</button>
<button type="button" class="btn btn-primary" disabled>btn-primary</button>
<button type="button" class="btn btn-danger" disabled>btn-danger</button>
<button type="button" class="btn btn-inverse" disabled>btn-inverse</button>
<button type="button" class="btn btn-outline" disabled>btn-outline</button>
<button type="button" class="btn btn-link" disabled>link</button>

Block Level Button

Adding .btn-block will span the width of the button to 100% of it's parent.

<button type="button" class="btn btn-default btn-block">btn-block</button>

To make a dropdown button wrap the tigger button in a container with the class dropdown and add a ul with class dropdow-menu. By default the menu is left aligned but can be changed by adding the class dropdown-menu-right to the dropdown menu.

To use dropdowns in navbars please see the Page Header Navigation section of the components section.

<div class="dropdown">
   <button type="button" class="btn btn-default">
     <svg class="cyclops-icon" aria-hidden="true"><use xlink:href='#icon-caret-down'></svg>
   <ul class="dropdown-menu">
     <li><a href="#">Action 1</a></li>
     <li><a href="#">Action 2</a></li>
     <li><a href="#">Action 3</a></li>

 <div class="dropdown">
   <button type="button" class="btn btn-default">
     Right Aligned
     <svg class="cyclops-icon" aria-hidden="true"><use xlink:href='#icon-caret-down'></svg>
   <ul class="dropdown-menu dropdown-menu-right">
     <li><a href="#">Action 1</a></li>
     <li><a href="#">Action 2</a></li>
     <li><a href="#">Action 3</a></li>
     <li role="separator" class="divider"></li>
     <li><a href="#">Action 4</a></li>
<!-- If the html is not present on page load you will need to
     either use the widget binding or call the widget directly
     on the button -->
  $('.dropdown button').dropdown()

Inline Text Button

When semantically it makes more sense to use a button instead of an a tag within a block of text, add the .btn-text-link class to match the text styles.

Paragraph of text with an within it.

<p>Paragraph of text with an <button class="btn btn-link-text">inline button link</button> within it.</p>

Inline Confirm

Inline confirm is a jQuery widget that can be applied to any button that will require the user to confirm the action they wish to perform. Typically this is used for Delete scenario's but can be used other places. Use it as a pure jQuery Widget or you can use the widget binding in knockout.

Inline confirm buttons can be created using jQuery or a Knockout binding.

For more informations about the options and how to consume it see the inlineConfirm Code Page.

<button class="btn btn-danger" data-bind="click: deleteHandler, widget:'inlineConfirm'">Delete</button>
anchor link to top of page
