Bootstrap Buttons
Button Styles
Bootstrap provides seven styles of buttons:
Default
Primary
Success
Info
Warning
Danger
Link
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
Small
XSmall
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>

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>
