Bootstrap Buttons

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


Torus Kit extends default Bootstrap “solid” and “outline” buttons with light, glow, button indicators and lot more.


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

<button type="button" class="btn btn-primary">Primary</button>
<button type="button" class="btn btn-secondary">Secondary</button>
<button type="button" class="btn btn-success">Success</button>
<button type="button" class="btn btn-danger">Danger</button>
<button type="button" class="btn btn-warning">Warning</button>
<button type="button" class="btn btn-info">Info</button>
<button type="button" class="btn btn-light">Light</button>
<button type="button" class="btn btn-dark">Dark</button>

<button type="button" class="btn btn-link">Link</button>
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.

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.

<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">

Light variations

Torus Kit brings new light style for default Bootstrap buttons. Use btn-{color}-light on .btn class to add some smoothness.

<button type="button" class="btn btn-primary-light">Primary</button>
<button type="button" class="btn btn-secondary-light">Secondary</button>
<button type="button" class="btn btn-success-light">Success</button>
<button type="button" class="btn btn-danger-light">Danger</button>
<button type="button" class="btn btn-warning-light">Warning</button>
<button type="button" class="btn btn-info-light">Info</button>
<button type="button" class="btn btn-grey-light">Grey</button>

Outline buttons

In need of a button, but not the hefty background colors they bring? Replace the default modifier classes with the .btn-outline-* ones to remove all background images and colors on any button.

<button type="button" class="btn btn-outline-primary">Primary</button>
<button type="button" class="btn btn-outline-secondary">Secondary</button>
<button type="button" class="btn btn-outline-success">Success</button>
<button type="button" class="btn btn-outline-danger">Danger</button>
<button type="button" class="btn btn-outline-warning">Warning</button>
<button type="button" class="btn btn-outline-info">Info</button>
<button type="button" class="btn btn-outline-light">Light</button>
<button type="button" class="btn btn-outline-dark">Dark</button>


Use .glow class on .btn to add a stylish glow effect. Hover effect automatically works on elements with .btn class.

<button type="button" class="btn glow btn-primary">Primary</button>
<button type="button" class="btn glow btn-secondary">Secondary</button>
<button type="button" class="btn glow btn-success">Success</button>
<button type="button" class="btn glow btn-danger">Danger</button>
<button type="button" class="btn glow btn-warning">Warning</button>
<button type="button" class="btn glow btn-info">Info</button>
<button type="button" class="btn glow btn-grey">Grey</button>


Add background fill effect on button hover or active state.

Solid buttons

Add .btn-fill class to .btn-{color} to set background fill effect.

<button type="button" class="btn btn-fill btn-primary">Primary</button>
<button type="button" class="btn btn-fill btn-secondary">Secondary</button>
<button type="button" class="btn btn-fill btn-success">Success</button>
<button type="button" class="btn btn-fill btn-danger">Danger</button>
<button type="button" class="btn btn-fill btn-warning">Warning</button>
<button type="button" class="btn btn-fill btn-info">Info</button>
<button type="button" class="btn btn-fill btn-grey">Grey</button>

Outline buttons

.btn-fill also works on .btn-outline-{color} classes. It automatically sets background color depending on button type.

<button type="button" class="btn btn-fill btn-outline-primary">Primary</button>
<button type="button" class="btn btn-fill btn-outline-secondary">Secondary</button>
<button type="button" class="btn btn-fill btn-outline-success">Success</button>
<button type="button" class="btn btn-fill btn-outline-danger">Danger</button>
<button type="button" class="btn btn-fill btn-outline-warning">Warning</button>
<button type="button" class="btn btn-fill btn-outline-info">Info</button>
<button type="button" class="btn btn-fill btn-outline-grey">Grey</button>

Skew effect

To create a skew effect, add btn-fill-skew class to .btn.

<button type="button" class="btn btn-fill-skew btn-primary">Primary</button>
<button type="button" class="btn btn-fill-skew btn-outline-primary">Primary</button>


Add some “3D” depth to a .btn with .btn-depth class.

<button type="button" class="btn btn-primary btn-depth">Primary</button>
<button type="button" class="btn btn-secondary btn-depth">Secondary</button>
<button type="button" class="btn btn-danger btn-depth">Danger</button>

With Icon

Add .btn-icon class for desired icon element that are wrapped in .btn. Font Awesome is supported as default, but other icon packs should work, too. Text content must be in <span> to provide consistent spacing.

<button type="button" class="btn btn-primary">
  <i class="fa fa-exclamation-triangle btn-icon"></i>
  <span>Icon left</span>

<button type="button" class="btn btn-secondary">
  <span>Icon right</span>
  <i class="fa fa-user btn-icon"></i>

<button class="btn btn-grey pos-rel">
  Notification icon
  <span class="circle bg-danger text-white p-3 shadow small pos-abs" data-position="right top" data-push="right-50 up-50">
    <i class="fa fa-exclamation-circle"></i>

Pill border

Even though buttons are rounded as default, sometimes it’s necessary to create a pill buttons. Use .rounded-pill class on .btn.

<button type="button" class="btn btn-primary rounded-pill">Primary</button>
<button type="button" class="btn btn-secondary rounded-pill">Secondary</button>
<button type="button" class="btn btn-danger rounded-pill">Danger</button>

<button type="button" class="btn btn-outline-primary rounded-pill">Primary</button>
<button type="button" class="btn btn-outline-secondary rounded-pill">Secondary</button>
<button type="button" class="btn btn-outline-danger rounded-pill">Danger</button>

Circle shape

Circle-shaped buttons are great when only an icon without any text is necessary. Torus Kit provide simple solution with no additional CSS styling needed. On .btn class use .circle along with .circle-{sm|md|lg|xl} according to desired button size. Read more about Torus Kit shapes.

<button type="button" class="btn btn-primary circle circle-md">
  <i class="fa fa-exclamation"></i>
<button type="button" class="btn btn-secondary circle circle-md">
  <i class="fa fa-exclamation-circle"></i>
<button type="button" class="btn btn-danger circle circle-md">
  <i class="fa fa-exclamation-triangle"></i>

Button indicators

Create CTA (call-to-action) buttons in a seconds using Torus Kit button indicators. No need to add any icons as these are using a Torus Kit Font. Icon color is inherited from a button text color.

Arrow indicator

When arrow icon indicator is required us .btn-arrow class on .btn.

<button type="button" class="btn btn-primary btn-arrow">Primary</button>
<button type="button" class="btn btn-secondary btn-arrow">Secondary</button>
<button type="button" class="btn btn-danger btn-arrow">Danger</button>

<button type="button" class="btn btn-outline-primary btn-arrow">Primary</button>
<button type="button" class="btn btn-outline-secondary btn-arrow">Secondary</button>
<button type="button" class="btn btn-outline-danger btn-arrow">Danger</button>

Chevron indicator

When chevron icon indicator is required us .btn-chevron class on .btn.

<button type="button" class="btn btn-primary btn-chevron">Primary</button>
<button type="button" class="btn btn-secondary btn-chevron">Secondary</button>
<button type="button" class="btn btn-danger btn-chevron">Danger</button>

<button type="button" class="btn btn-outline-primary btn-chevron">Primary</button>
<button type="button" class="btn btn-outline-secondary btn-chevron">Secondary</button>
<button type="button" class="btn btn-outline-danger btn-chevron">Danger</button>


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

<button type="button" class="btn btn-primary btn-lg">Large button</button>
<button type="button" class="btn btn-secondary btn-lg">Large button</button>
<button type="button" class="btn btn-primary btn-sm">Small button</button>
<button type="button" class="btn btn-secondary btn-sm">Small button</button>

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-secondary btn-lg btn-block">Block level button</button>

When using .btn-block together with .btn-arrow or .btn-chevron it may be necessary to expand content to sides. Use .justify-content-between flex utility. Note, that it works only with Torus Kit as default Bootstrap buttons doesn’t use flex.

<button type="button" class="btn btn-primary btn-lg btn-block btn-arrow justify-content-between">Block level button</button>
<button type="button" class="btn btn-secondary btn-lg btn-block btn-chevron justify-content-between">Block level button</button>

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.

<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>

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>

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.
<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>

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" autocomplete="off">
  Single toggle

Checkbox and radio buttons

Bootstrap’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-toggle" data-toggle="buttons">
  <label class="btn btn-secondary active">
    <input type="checkbox" checked autocomplete="off"> Checked
<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 class="btn btn-secondary">
    <input type="radio" name="options" id="option2" autocomplete="off"> Radio
  <label class="btn btn-secondary">
    <input type="radio" name="options" id="option3" autocomplete="off"> Radio
