Forms

Basic example

Individual form controls automatically receive some global styling. All textual <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.

Example block-level help text here.

Inline form

Add .form-inline to your <form> for left-aligned and inline-block controls. This only applies to forms within viewports that are at least 768px wide.

Horizontal form

Use Bootstrap's predefined grid classes to align labels and groups of form controls in a horizontal layout by adding .form-horizontal to the form. Doing so changes .form-groups to behave as grid rows, so no need for .row.

Supported controls

Examples of standard form controls supported in an example form layout.

Inputs

Most common form control, text-based input fields. Includes support for all HTML5 types: text, password, datetime, datetime-local, date, month, time, week, number, email, url, search, tel, and color.

Textarea

Form control which supports multiple lines of text. Change rows attribute as necessary.

Checkboxes and radios

Checkboxes are for selecting one or several options in a list while radios are for selecting one option from many.

Default (stacked)


Inline checkboxes

Use the .checkbox-inline or .radio-inline classes on a series of checkboxes or radios for controls that appear on the same line.

Selects

Use the default option, or add multiple to show multiple options at once.


Static control

When you need to place plain text next to a form label within a horizontal form, use the .form-control-static class on a <p>.

Input focus

We remove the default outline styles on some form controls and apply a box-shadow in its place for :focus.

Demo :focus state

The above example input uses custom styles in our documentation to demonstrate the :focus state on a .form-control.

Validation states

Bootstrap includes validation styles for error, warning, and success states on form controls. To use, add .has-warning, .has-error, or .has-success to the parent element. Any .control-label, .form-control, and .help-block within that element will receive the validation styles.

Control sizing

Set heights using classes like .input-lg, and set widths using grid column classes like .col-lg-*.

Height sizing

Create taller or shorter form controls that match button sizes.Border radius can be changed using .border-radius class.

Column sizing

Wrap inputs in grid columns, or any custom parent element, to easily enforce desired widths.

Help text

Block level help text for form controls.

A block of help text that breaks onto a new line and may extend beyond one line.
