Bootstrap includes six predefined button styles, each serving its own semantic purpose.
Fancy larger or smaller buttons? Add
.btn-lg or .btn-sm for additional sizes.
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.
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).
Make buttons look inactive by adding the disabled boolean attribute to any <button> element.
Disabled buttons using the <a> element behave a bit different:
Create block level buttons—those that
span the full width of a parent—by adding .btn-block.
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>.
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.

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..
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.
