input
, textarea
, and select
elements with .form-control
are set to width: 100%;
by default. Wrap labels and controls in .form-group for optimum spacing.Extend form controls by adding text or buttons before, after, or on both sides of any text-based input. Use .input-group
with an .input-group-addon
to prepend or append elements to a .form-control
.
Buttons in input groups are a bit different and require one extra level of nesting. Instead of .input-group-addon
, you'll need to use .input-group-btn
to wrap the buttons. This is required due to default browser styles that cannot be overridden.

, and .help-block
within that element will receive the validation styles.
