Buttons
Use Bootstrap’s custom button styles for actions in forms, dialogs, and more with support for multiple sizes, states, and more.
Examples
Bootstrap includes several predefined button styles, each serving its own semantic purpose, with a few extras thrown in for more control.
type="button" class="btn btn-primary">Primary type="button" class="btn btn-secondary">Secondary type="button" class="btn btn-success">Success type="button" class="btn btn-danger">Danger type="button" class="btn btn-warning">Warning type="button" class="btn btn-info">Info type="button" class="btn btn-light">Light type="button" class="btn btn-dark">Dark type="button" class="btn btn-link">Link 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 element. However, you can also use these classes on or elements (though some browsers may apply a slightly different rendering).
class="btn btn-primary" href="#" role="button">Link class="btn btn-primary" type="submit">Button class="btn btn-primary" type="button" value="Input"> class="btn btn-primary" type="submit" value="Submit"> class="btn btn-primary" type="reset" value="Reset">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.
type="button" class="btn btn-outline-primary">Primary type="button" class="btn btn-outline-secondary">Secondary type="button" class="btn btn-outline-success">Success type="button" class="btn btn-outline-danger">Danger type="button" class="btn btn-outline-warning">Warning type="button" class="btn btn-outline-info">Info type="button" class="btn btn-outline-light">Light type="button" class="btn btn-outline-dark">Dark Sizes
Fancy larger or smaller buttons? Add .btn-lg or .btn-sm for additional sizes.
type="button" class="btn btn-primary btn-lg">Large button type="button" class="btn btn-secondary btn-lg">Large button type="button" class="btn btn-primary btn-sm">Small button type="button" class="btn btn-secondary btn-sm">Small button Create block level buttons—those that span the full width of a parent—by adding .btn-block .
type="button" class="btn btn-primary btn-lg btn-block">Block level button type="button" class="btn btn-secondary btn-lg btn-block">Block level 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 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.
href="#" class="btn btn-primary btn-lg active" role="button" aria-pressed="true">Primary link href="#" class="btn btn-secondary btn-lg active" role="button" aria-pressed="true">Link Disabled state
Make buttons look inactive by adding the disabled boolean attribute to any element.
type="button" class="btn btn-lg btn-primary" disabled>Primary button type="button" class="btn btn-secondary btn-lg" disabled>Button href="#" class="btn btn-primary btn-lg disabled" role="button" aria-disabled="true">Primary link href="#" class="btn btn-secondary btn-lg disabled" role="button" aria-disabled="true">Link Link functionality caveat
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 .
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 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 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 or by manually applying the input’s checked property—you’ll need to toggle .active on the manually.
Note that pre-checked buttons require you to manually add the .active class to the input’s .
class="btn-group-toggle" data-toggle="buttons"> class="btn btn-secondary active"> type="checkbox" checked autocomplete="off"> Checked class="btn-group btn-group-toggle" data-toggle="buttons"> class="btn btn-secondary active"> type="radio" name="options" id="option1" autocomplete="off" checked> Active class="btn btn-secondary"> type="radio" name="options" id="option2" autocomplete="off"> Radio class="btn btn-secondary"> type="radio" name="options" id="option3" autocomplete="off"> Radio Methods
| Method | Description |
|---|---|
| $().button(‘toggle’) | Toggles push state. Gives the button the appearance that it has been activated. |
| $().button(‘dispose’) | Destroys an element’s button. |
Button group
Group a series of buttons together on a single line with the button group, and super-power them with JavaScript.
Basic example
Wrap a series of buttons with .btn in .btn-group . Add on optional JavaScript radio and checkbox style behavior with our buttons plugin.
class="btn-group" role="group" aria-label="Basic example"> type="button" class="btn btn-secondary">Left type="button" class="btn btn-secondary">Middle type="button" class="btn btn-secondary">Right Ensure correct role and provide a label
In order for assistive technologies (such as screen readers) to convey that a series of buttons is grouped, an appropriate role attribute needs to be provided. For button groups, this would be role=»group» , while toolbars should have a role=»toolbar» .
In addition, groups and toolbars should be given an explicit label, as most assistive technologies will otherwise not announce them, despite the presence of the correct role attribute. In the examples provided here, we use aria-label , but alternatives such as aria-labelledby can also be used.
Button toolbar
Combine sets of button groups into button toolbars for more complex components. Use utility classes as needed to space out groups, buttons, and more.
class="btn-toolbar" role="toolbar" aria-label="Toolbar with button groups"> class="btn-group mr-2" role="group" aria-label="First group"> type="button" class="btn btn-secondary">1 type="button" class="btn btn-secondary">2 type="button" class="btn btn-secondary">3 type="button" class="btn btn-secondary">4 class="btn-group mr-2" role="group" aria-label="Second group"> type="button" class="btn btn-secondary">5 type="button" class="btn btn-secondary">6 type="button" class="btn btn-secondary">7 class="btn-group" role="group" aria-label="Third group"> type="button" class="btn btn-secondary">8 Feel free to mix input groups with button groups in your toolbars. Similar to the example above, you’ll likely need some utilities though to space things properly.
class="btn-toolbar mb-3" role="toolbar" aria-label="Toolbar with button groups"> class="btn-group mr-2" role="group" aria-label="First group"> type="button" class="btn btn-secondary">1 type="button" class="btn btn-secondary">2 type="button" class="btn btn-secondary">3 type="button" class="btn btn-secondary">4 class="input-group"> class="input-group-prepend"> class="input-group-text" id="btnGroupAddon">@ type="text" class="form-control" placeholder="Input group example" aria-label="Input group example" aria-describedby="btnGroupAddon"> class="btn-toolbar justify-content-between" role="toolbar" aria-label="Toolbar with button groups"> class="btn-group" role="group" aria-label="First group"> type="button" class="btn btn-secondary">1 type="button" class="btn btn-secondary">2 type="button" class="btn btn-secondary">3 type="button" class="btn btn-secondary">4 class="input-group"> class="input-group-prepend"> class="input-group-text" id="btnGroupAddon2">@ type="text" class="form-control" placeholder="Input group example" aria-label="Input group example" aria-describedby="btnGroupAddon2"> Sizing
Instead of applying button sizing classes to every button in a group, just add .btn-group-* to each .btn-group , including each one when nesting multiple groups.
class="btn-group btn-group-lg" role="group" aria-label=". ">. class="btn-group" role="group" aria-label=". ">. class="btn-group btn-group-sm" role="group" aria-label=". ">. Nesting
Place a .btn-group within another .btn-group when you want dropdown menus mixed with a series of buttons.
class="btn-group" role="group" aria-label="Button group with nested dropdown"> type="button" class="btn btn-secondary">1 type="button" class="btn btn-secondary">2 class="btn-group" role="group"> id="btnGroupDrop1" type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"> Dropdown class="dropdown-menu" aria-labelledby="btnGroupDrop1"> class="dropdown-item" href="#">Dropdown link class="dropdown-item" href="#">Dropdown link Vertical variation
Make a set of buttons appear vertically stacked rather than horizontally. Split button dropdowns are not supported here.
