Buttons
Examples
Bootstrap includes several predefined button styles, each serving its own semantic purpose.
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 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).
Sizes
Fancy larger or smaller buttons? Add .btn-lg or
.btn-sm for additional sizes.
Disabled Buttons
Make buttons look inactive by adding the disabled boolean
attribute to any <button> element.
Disabled Links
<a>s don’t support the disabled attribute,
so you must add the .disabled class to make it
visually appear disabled.
Block Buttons
Create block level buttons—those that span the full width of a
parent—by adding .btn-block.
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>.
Checkbox 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 toggling in their respective styles.
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 toggling in their respective styles.
Input With Button Groups
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..
Button Groups
Place a .btn-group within another
.btn-group when you want dropdown menus mixed
with a series of buttons.Make a set of buttons appear
vertically stacked rather than horizontally.
