Bootstrap button css styles

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

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.

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 element. However, you can also use these classes on or elements (though some browsers may apply a slightly different rendering).

a class="btn btn-primary" href="#" role="button">Linka> button class="btn btn-primary" type="submit">Buttonbutton> 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">

button type="button" class="btn btn-outline-primary">Primarybutton> button type="button" class="btn btn-outline-secondary">Secondarybutton> button type="button" class="btn btn-outline-success">Successbutton> button type="button" class="btn btn-outline-danger">Dangerbutton> button type="button" class="btn btn-outline-warning">Warningbutton> button type="button" class="btn btn-outline-info">Infobutton> button type="button" class="btn btn-outline-light">Lightbutton> button type="button" class="btn btn-outline-dark">Darkbutton>

Some of the button styles use a relatively light foreground color, and should only be used on a dark background in order to have sufficient contrast.

Sizes

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

button type="button" class="btn btn-primary btn-lg">Large buttonbutton> button type="button" class="btn btn-secondary btn-lg">Large buttonbutton>

button type="button" class="btn btn-primary btn-sm">Small buttonbutton> button type="button" class="btn btn-secondary btn-sm">Small buttonbutton>

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 buttonbutton> button type="button" class="btn btn-secondary btn-lg btn-block">Block level buttonbutton>

Active state

Buttons will appear pressed when active with a darker background, darker border, and, when shadows are enabled, an inset shadow. 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.

a href="#" class="btn btn-primary btn-lg active" role="button" aria-pressed="true">Primary linka> a href="#" class="btn btn-secondary btn-lg active" role="button" aria-pressed="true">Linka>

Disabled state

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

button type="button" class="btn btn-lg btn-primary" disabled>Primary buttonbutton> button type="button" class="btn btn-secondary btn-lg" disabled>Buttonbutton>

a class="btn btn-primary btn-lg disabled" role="button" aria-disabled="true">Primary linka> a class="btn btn-secondary btn-lg disabled" role="button" aria-disabled="true">Linka>

Link functionality caveat

a href="#" class="btn btn-primary btn-lg disabled" tabindex="-1" role="button" aria-disabled="true">Primary linka> a href="#" class="btn btn-secondary btn-lg disabled" tabindex="-1" role="button" aria-disabled="true">Linka>
