<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="reset" value="Reset">
<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-warning">btn-warning</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>

<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>

Buttons with Icons

Svg icons maybe placed within a button or a tag, and will be automatically sized based on the button size specified.

<button type="button" class="btn btn-primary">
  <svg class="cyclops-icon" aria-hidden="true"><use xlink:href='#icon-plus-circle' /></svg> add item

Icon Buttons

To use an svg icon as a button, wrap the <svg> with <button> and apply .btn and .btn-* to apply the approprite fill color. Icon buttons may also be sized using .btn-sm and .btn-lg.

Include Button Label Text for Accessibility

Be sure to include text inside the button element for screen readers by using .sr-only.

<!-- small grey x icon button -->
<button class="btn btn-default btn-sm btn-icon">
  <svg class="cyclops-icon" aria-hidden="true"><use xlink:href='#icon-times' /></svg>
  <span class="sr-only">remove</span>

<!-- default sized green x icon button -->
<button class="btn btn-primary btn-icon">
  <svg class="cyclops-icon" aria-hidden="true"><use xlink:href='#icon-times' /></svg>
  <span class="sr-only">remove</span>

<!-- large red x icon button -->
<button class="btn btn-danger btn-lg btn-icon">
  <svg class="cyclops-icon" aria-hidden="true"><use xlink:href='#icon-times' /></svg>
  <span class="sr-only">remove</span>

Button Group

Group buttons together using .btn-group to wrap a series of buttons. They may include button dropdowns as well.

<div class="btn-group">
  <button class="btn btn-outline">first</button>
  <button class="btn btn-outline active">active</button>
  <button class="btn btn-outline">third</button>
  <div class="dropdown">
    <button type="button" class="btn btn-outline">
      <svg class="cyclops-icon" aria-hidden="true"><use xlink:href='#icon-caret-down' /></svg>
    <ul class="dropdown-menu">
  <button class="btn btn-outline">fifth</button>

Inline Text Button

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 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>
