Bootstrap Buttons


Button Styles

Bootstrap provides seven styles of buttons:

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:

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.

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:

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>
