Buttons

Use Boosted’s custom button styles for actions in forms, dialogs, and more with support for multiple sizes, states, and more.

Examples

Boosted includes several predefined button styles, each serving its own semantic purpose, with a few extras thrown in for more control.

Conveying meaning to assistive technologies

Using color to add meaning only provides a visual indication, which will not be conveyed to users of assistive technologies – such as screen readers. Ensure that information denoted by the color is either obvious from the content itself (e.g. the visible text), or is included through alternative means, such as additional text hidden with the .sr-only class.

Dark backgrounds

To get the inversed button behaviour, simply add .btn-inverse class to your <button> or <a> tag.

<div class="bg-dark p-3">
    <button type="button" class="btn btn-inverse btn-primary">Primary</button>
    <button type="button" class="btn btn-inverse btn-secondary">Secondary</button>
    <button type="button" class="btn btn-inverse btn-success">Success</button>
    <button type="button" class="btn btn-inverse btn-danger">Danger</button>
    <button type="button" class="btn btn-inverse btn-warning">Warning</button>
    <button type="button" class="btn btn-inverse btn-info">Info</button>
    <button type="button" class="btn btn-inverse btn-link">Link</button>
    <button type="button" class="btn btn-inverse btn-secondary btn-icon">
        <span class="sr-only">Icon</span>
        <span class="icon icon-settings" aria-hidden="true"></span>
    </button>
    <br><br>
    <button type="button" class="btn btn-inverse btn-primary">
        <span class="icon icon-settings" aria-hidden="true"></span>
        Primary
    </button>
    <button type="button" class="btn btn-inverse btn-secondary">
        <span class="icon icon-settings" aria-hidden="true"></span>
        Secondary
    </button>
    <button type="button" class="btn btn-inverse btn-success">
        <span class="icon icon-settings" aria-hidden="true"></span>
        Success
    </button>
    <button type="button" class="btn btn-inverse btn-danger">
        <span class="icon icon-settings" aria-hidden="true"></span>
        Danger
    </button>
    <button type="button" class="btn btn-inverse btn-warning">
        <span class="icon icon-settings" aria-hidden="true"></span>
        Warning
    </button>
    <button type="button" class="btn btn-inverse btn-info">
        <span class="icon icon-settings" aria-hidden="true"></span>
        Info
    </button>
</div>

In need of a social media button? Some helper classes are designed to be used along with the .btn element, starting with the .btn-social variant.

<div class="p-3">
    <a class="btn btn-social btn-twitter" href="#"><span class="sr-only">Twitter</span></a> 
    <a class="btn btn-social btn-facebook" href="#"><span class="sr-only">Facebook</span></a>
    <a class="btn btn-social btn-instagram" href="#"><span class="sr-only">Instagram</span></a>
    <a class="btn btn-social btn-whatsapp" href="#"><span class="sr-only">Whatsapp</span></a> 
    <a class="btn btn-social btn-linkedin" href="#"><span class="sr-only">Linkedin</span></a>    
    <a class="btn btn-social btn-youtube" href="#"><span class="sr-only">YouTube</span></a> 
    <a class="btn btn-social btn-snapchat" href="#"><span class="sr-only">Snapchat</span></a> 
    <a class="btn btn-social btn-pinterest" href="#"><span class="sr-only">Pinterest</span></a> 
    <a class="btn btn-social btn-mail" href="#"><span class="sr-only">Mail</span></a>
</div>
<div class="bg-dark p-3">
    <a class="btn btn-inverse btn-social btn-twitter" href="#"><span class="sr-only">Twitter</span></a> 
    <a class="btn btn-inverse btn-social btn-facebook" href="#"><span class="sr-only">Facebook</span></a>
    <a class="btn btn-inverse btn-social btn-instagram" href="#"><span class="sr-only">Instagram</span></a>
    <a class="btn btn-inverse btn-social btn-whatsapp" href="#"><span class="sr-only">Whatsapp</span></a> 
    <a class="btn btn-inverse btn-social btn-linkedin" href="#"><span class="sr-only">Linkedin</span></a>    
    <a class="btn btn-inverse btn-social btn-youtube" href="#"><span class="sr-only">YouTube</span></a> 
    <a class="btn btn-inverse btn-social btn-snapchat" href="#"><span class="sr-only">Snapchat</span></a> 
    <a class="btn btn-inverse btn-social btn-pinterest" href="#"><span class="sr-only">Pinterest</span></a> 
    <a class="btn btn-inverse btn-social btn-mail" href="#"><span class="sr-only">Mail</span></a>
</div>

Social buttons are compatibles with dark backgrounds variant and sizing utilities.

Disable text wrapping

If you don’t want the button text to wrap, you can add the .text-nowrap class to the button. In Sass, you can set $btn-white-space: nowrap to disable text wrapping for each button.

Button tags

The .btn classes are designed to be used with the <button> element. However, you can also use these classes on <a> or <input> elements (though some browsers may apply a slightly different rendering).

When using button classes on <a> elements that are used to trigger in-page functionality (like collapsing content), rather than linking to new pages or sections within the current page, these links should be given a role="button" to appropriately convey their purpose to assistive technologies such as screen readers.

Link

<a class="btn btn-primary" href="#" role="button">Link</a>
<button class="btn btn-primary" type="submit">Button</button>
<input class="btn btn-primary" type="button" value="Input">
<input class="btn btn-primary" type="submit" value="Submit">
<input class="btn btn-primary" type="reset" value="Reset">

Sizes

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

Medium button is the standard button size.

<button type="button" class="btn btn-primary btn-sm">Small button</button>
<button type="button" class="btn btn-primary">Medium button</button>
<button type="button" class="btn btn-primary btn-lg">Large button</button>
<div class="bg-dark p-3 mt-3">
  <button type="button" class="btn btn-primary btn-inverse btn-sm">Small button</button>
  <button type="button" class="btn btn-primary btn-inverse">Medium button</button>
  <button type="button" class="btn btn-primary btn-inverse btn-lg">Large button</button>
</div>

<button type="button" class="btn btn-secondary btn-sm">Small button</button>
<button type="button" class="btn btn-secondary">Medium button</button>
<button type="button" class="btn btn-secondary btn-lg">Large button</button>
<div class="bg-dark p-3 mt-3">
  <button type="button" class="btn btn-secondary btn-inverse btn-sm">Small button</button>
  <button type="button" class="btn btn-secondary btn-inverse">Medium button</button>
  <button type="button" class="btn btn-secondary btn-inverse btn-lg">Large button</button>
</div>

Active state

Buttons will appear pressed (with a darker background, darker border, and inset shadow) when active. There’s no need to add a class to <button>s as they use a pseudo-class. However, you can still force the same active appearance with .active (and include the aria-pressed="true" attribute) should you need to replicate the state programmatically.

Primary link Link

<a href="#" class="btn btn-primary btn-lg active" role="button" aria-pressed="true">Primary link</a>
<a href="#" class="btn btn-secondary btn-lg active" role="button" aria-pressed="true">Link</a>
<div class="bg-dark p-3 mt-3">
  <a href="#" class="btn btn-primary btn-inverse btn-lg active" role="button" aria-pressed="true">Primary link</a>
  <a href="#" class="btn btn-secondary btn-inverse btn-lg active" role="button" aria-pressed="true">Link</a>
</div>

Disabled state

Make buttons look inactive by adding the disabled boolean attribute to any <button> element.

<button type="button" class="btn btn-lg btn-primary" disabled>Primary button</button>
<button type="button" class="btn btn-secondary btn-lg" disabled>Button</button>
<div class="bg-dark p-3 mt-3">
    <button type="button" class="btn btn-primary btn-inverse btn-lg" disabled>Primary button</button>
    <button type="button" class="btn btn-secondary btn-inverse btn-lg" disabled>Button</button>
</div>

Disabled buttons using the <a> element behave a bit different:

<a>s don’t support the disabled attribute, so you must add the .disabled class to make it visually appear disabled.
Some future-friendly styles are included to disable all pointer-events on anchor buttons. In browsers which support that property, you won’t see the disabled cursor at all.
Disabled buttons should include the aria-disabled="true" attribute to indicate the state of the element to assistive technologies.

Primary link Link

<a href="#" class="btn btn-primary btn-lg disabled" tabindex="-1" role="button" aria-disabled="true">Primary link</a>
<a href="#" class="btn btn-secondary btn-lg disabled" tabindex="-1" role="button" aria-disabled="true">Link</a>

Link functionality caveat

The .disabled class uses pointer-events: none to try to disable the link functionality of <a>s, but that CSS property is not yet standardized. In addition, even in browsers that do support pointer-events: none, keyboard navigation remains unaffected, meaning that sighted keyboard users and users of assistive technologies will still be able to activate these links. So to be safe, add a tabindex="-1" attribute on these links (to prevent them from receiving keyboard focus) and use custom JavaScript to disable their functionality.

Button plugin

Do more with buttons. Control button states or create groups of buttons for more components like toolbars.

Toggle states

Add data-toggle="button" to toggle a button’s active state. If you’re pre-toggling a button, you must manually add the .active class and aria-pressed="true" to the <button>.

<button type="button" class="btn btn-primary" data-toggle="button" aria-pressed="false">
  Single toggle
</button>

Checkbox and radio buttons

Boosted’s .button styles can be applied to other elements, such as <label>s, to provide checkbox or radio style button toggling. Add data-toggle="buttons" to a .btn-group containing those modified buttons to enable their toggling behavior via JavaScript and add .btn-group-toggle to style the <input>s within your buttons. Note that you can create single input-powered buttons or groups of them.

The checked state for these buttons is only updated via click event on the button. If you use another method to update the input—e.g., with <input type="reset"> or by manually applying the input’s checked property—you’ll need to toggle .active on the <label> manually.

Note that pre-checked buttons require you to manually add the .active class to the input’s <label>.

<div class="btn-group btn-group-toggle" data-toggle="buttons">
  <label class="btn btn-secondary active">
    <input type="radio" name="options" id="option1" autocomplete="off" checked> Active
  </label>
  <label class="btn btn-secondary">
    <input type="radio" name="options" id="option2" autocomplete="off"> Radio
  </label>
  <label class="btn btn-secondary">
    <input type="radio" name="options" id="option3" autocomplete="off"> Radio
  </label>
</div>
<div class="bg-dark p-3">
    <div class="btn-group btn-group-toggle" data-toggle="buttons">
      <label class="btn btn-secondary btn-inverse active">
        <input type="radio" name="options-dark" id="option4" autocomplete="off" checked> Active
      </label>
      <label class="btn btn-secondary btn-inverse">
        <input type="radio" name="options-dark" id="option5" autocomplete="off"> Radio
      </label>
      <label class="btn btn-secondary btn-inverse">
        <input type="radio" name="options-dark" id="option6" autocomplete="off"> Radio
      </label>
    </div>
</div>
