<p>Bootstrap’s form controls expand on <a href="/docs/4.0/content/reboot/#forms">our Rebooted form styles</a> with classes. Use these classes to opt into their customized displays for a more consistent rendering across browsers and devices.</p>
<p>Be sure to use an appropriate <code class="highlighter-rouge">type</code> attribute on all inputs (e.g., <code class="highlighter-rouge">email</code> for email address or <code class="highlighter-rouge">number</code> for numerical information) to take advantage of newer input controls like email verification, number selection, and more.</p>
<p>Here’s a quick example to demonstrate Bootstrap’s form styles. Keep reading for documentation on required classes, form layout, and more.</p>

<p>Default checkboxes and radios are improved upon with the help of <code class="highlighter-rouge">.form-check</code>, <strong>a single class for both input types that improves the layout and behavior of their HTML elements</strong>. Checkboxes are for selecting one or several options in a list, while radios are for selecting one option from many.</p>
<p>Disabled checkboxes and radios are supported, but to provide a <code class="highlighter-rouge">not-allowed</code> cursor on hover of the parent <code class="highlighter-rouge"><label></code>, you’ll need to add the <code class="highlighter-rouge">disabled</code> attribute to the <code class="highlighter-rouge">.form-check-input</code>. The disabled attribute will apply a lighter color to help indicate the input’s state.</p>
<p>Checkboxes and radios use are built to support HTML-based form validation and provide concise, accessible labels. As such, our <code class="highlighter-rouge"><input></code>s and <code class="highlighter-rouge"><label></code>s are sibling elements as opposed to an <code class="highlighter-rouge"><input></code> within a <code class="highlighter-rouge"><label></code>. This is slightly more verbose as you must specify <code class="highlighter-rouge">id</code> and <code class="highlighter-rouge">for</code> attributes to relate the <code class="highlighter-rouge"><input></code> and <code class="highlighter-rouge"><label></code>.</p>
<h3 id="default-stacked"><div>Default (stacked)<a class="anchorjs-link " href="#default-stacked" aria-label="Anchor" data-anchorjs-icon="#" style="padding-left: 0.375em;"></a></div></h3>
<p>By default, any number of checkboxes and radios that are immediate sibling will be vertically stacked and appropriately spaced with <code class="highlighter-rouge">.form-check</code>.</p>

<h2 id="layout"><div>Layout<a class="anchorjs-link " href="#layout" aria-label="Anchor" data-anchorjs-icon="#" style="padding-left: 0.375em;"></a></div></h2>
<p>Since Bootstrap applies <code class="highlighter-rouge">display: block</code> and <code class="highlighter-rouge">width: 100%</code> to almost all our form controls, forms will by default stack vertically. Additional classes can be used to vary this layout on a per-form basis.</p>
<h3 id="form-groups"><div>Form groups<a class="anchorjs-link " href="#form-groups" aria-label="Anchor" data-anchorjs-icon="#" style="padding-left: 0.375em;"></a></div></h3>
<p>The <code class="highlighter-rouge">.form-group</code> class is the easiest way to add some structure to forms. It provides a flexible class that encourages proper grouping of labels, controls, optional help text, and form validation messaging. By default it only applies <code class="highlighter-rouge">margin-bottom</code>, but it picks up additional styles in <code class="highlighter-rouge">.form-inline</code> as needed. Use it with <code class="highlighter-rouge"><fieldset></code>s, <code class="highlighter-rouge"><div></code>s, or nearly any other element.</p>
