Button Styles
Bootstrap provides seven styles of buttons:

Default Primary SuccessInfo Warning DangerLink

To achieve the button styles above, Bootstrap has the following classes:

.btn-default
.btn-primary
.btn-success
.btn-info
.btn-warning
.btn-danger
.btn-link
The following example shows the code for the different button styles:

Example
<button type="button" class="btn btn-default">Default</button>
<button type="button" class="btn btn-primary">Primary</button>
<button type="button" class="btn btn-success">Success</button>
<button type="button" class="btn btn-info">Info</button>
<button type="button" class="btn btn-warning">Warning</button>
<button type="button" class="btn btn-danger">Danger</button>
<button type="button" class="btn btn-link">Link</button>
»
The button classes can be used on an <a>, <button>, or <input> element:

Example
<a href="#" class="btn btn-info" role="button">Link Button</a>
<button type="button" class="btn btn-info">Button</button>
<input type="button" class="btn btn-info" value="Input Button">
<input type="submit" class="btn btn-info" value="Submit Button">
»
Why do we put a # in the href attribute of the link?

Since we do not have any page to link it to, and we do not want to get a "404" message, we put # as the link. In real life it should of course been a real URL to the "Search" page.

Button Sizes
Bootstrap provides four button sizes:

Large Medium SmallXSmall

The classes that define the different sizes are:

.btn-lg
.btn-md
.btn-sm
.btn-xs
The following example shows the code for different button sizes:

Example
<button type="button" class="btn btn-primary btn-lg">Large</button>
<button type="button" class="btn btn-primary btn-md">Medium</button>
<button type="button" class="btn btn-primary btn-sm">Small</button>
<button type="button" class="btn btn-primary btn-xs">XSmall</button>
»
Block Level Buttons
A block level button spans the entire width of the parent element.

Button 1
Button 2
Add class .btn-block to create a block level button:

Example
<button type="button" class="btn btn-primary btn-block">Button 1</button>
»
Active/Disabled Buttons
A button can be set to an active (appear pressed) or a disabled (unclickable) state:

Active Primary Disabled Primary

The class .active makes a button appear pressed, and the class .disabled makes a button unclickable:

Example
<button type="button" class="btn btn-primary active">Active Primary</button>
<button type="button" class="btn btn-primary disabled">Disabled Primary</button>
