Buttons
This is sub heading text to describe the page functionality
How it Works
Use the button classes on an <a>
, <button>
, or <input>
element.
<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">
Options
Use any of the available button classes to quickly create a styled button.
Default
Primary
Success
Info
Warning
Danger
Link
<!-- Standard button -->
<button type="button" class="btn btn-default"> Default</button>
<!-- Provides extra visual weight and identifies the primary action in a set of buttons -->
<button type="button" class="btn btn-primary"> Primary</button>
<!-- Indicates a successful or positive action -->
<button type="button" class="btn btn-success"> Success</button>
<!-- Contextual button for informational alert messages -->
<button type="button" class="btn btn-info"> Info</button>
<!-- Indicates caution should be taken with this action -->
<button type="button" class="btn btn-warning"> Warning</button>
<!-- Indicates a dangerous or potentially negative action -->
<button type="button" class="btn btn-danger"> Danger</button>
<!-- Deemphasize a button by making it look like a link while maintaining button behavior -->
<button type="button" class="btn btn-link"> Link</button>
Block Buttons
Create block level buttons—those that span the full width of a
parent— by adding .btn-block
.

<button type="button" class="btn btn-primary btn-lg btn-block"> Block level button</button>
<button type="button" class="btn btn-default btn-lg btn-block"> Block level button</button>
Buttons will appear pressed (with a darker background, darker border,
and inset shadow) when active. For <button>
elements, this
is done via :active
. For <a>
elements, it's done
with .active
. However, you may use .active
on
<button>
s (and include the aria-pressed="true"
attribute) should you need to replicate the active state programmatically.
Button element
No need to add :active
as it's a pseudo-class, but if you
need to force the same appearance, go ahead and add .active
.
Primary button
Button
<button type="button" class="btn btn-primary btn-lg active"> Primary button</button>
<button type="button" class="btn btn-default btn-lg active"> Button</button>
Anchor element
Add the .active
class to <a>
buttons.
Primary link
Link
<a href="#" class="btn btn-primary btn-lg active" role="button"> Primary link</a>
<a href="#" class="btn btn-default btn-lg active" role="button"> Link</a>
Disabled state
Make buttons look unclickable by fading them back with opacity
.
Button element
Add the disabled
attribute to <button>
buttons.
Primary button
Button
<button type="button" class="btn btn-lg btn-primary" disabled="disabled"> Primary button</button>
<button type="button" class="btn btn-default btn-lg" disabled="disabled"> Button</button>
Anchor element
Add the .disabled
class to <a>
buttons.
Primary link
Link
<a href="#" class="btn btn-primary btn-lg disabled" role="button"> Primary link</a>
<a href="#" class="btn btn-default btn-lg disabled" role="button"> Link</a>
We use .disabled
as a utility class here, similar to the
common .active
class, so no prefix is required.
