Bootstrap Buttons
Button Styles
Bootstrap provides different styles of buttons:
To achieve the button styles above, Bootstrap has the following classes:
.btn.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">Basic</button>
<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 our examples. It should be a real URL to a
specific page.
Button Sizes
Bootstrap provides four button sizes:
The classes that define the different sizes are:
.btn-lg.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">Normal</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.
Add class .btn-block to create a block level button:
Active/Disabled Buttons
A button can be set to an active (appear pressed) or a disabled (unclickable) state:
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>
