#### Button Tags

Use the button classes on an `<a>`, `<button>`, or `<input>` element.

Link

    <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">

#### Button Options

Use any of the available button classes to quickly create a styled button.

    <!-- 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>

#### Button Sizes

Fancy larger or smaller buttons? Add `.btn-lg`, `.btn-sm`, or `.btn-xs` for additional sizes.

    <p>
        <button type="button" class="btn btn-primary btn-lg">Large button</button>
        <button type="button" class="btn btn-default btn-lg">Large button</button>
    </p>
    <p>
        <button type="button" class="btn btn-primary">Default button</button>
        <button type="button" class="btn btn-default">Default button</button>
    </p>
    <p>
        <button type="button" class="btn btn-primary btn-sm">Small button</button>
        <button type="button" class="btn btn-default btn-sm">Small button</button>
    </p>
    <p>
        <button type="button" class="btn btn-primary btn-xs">Extra small button</button>
        <button type="button" class="btn btn-default btn-xs">Extra small button</button>
    </p>

#### Block Level 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>

#### Active State of Buttons

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 type="button" class="btn btn-primary active">Primary button</button>
    <button type="button" class="btn btn-default active">Button</button>

#### Disabled State of Buttons

Make buttons look un-clickable by fading them back with opacity. Add the disabled attribute to `<button>` buttons.

    <button type="button" class="btn btn-primary" disabled="disabled">Primary button</button>
    <button type="button" class="btn btn-default" disabled="disabled">Button</button>
