  <h2 id="forms-example">Basic example</h2>
  <p>Individual form controls automatically receive some global styling. All textual <code>&lt;input&gt;</code>, <code>&lt;textarea&gt;</code>, and <code>&lt;select&gt;</code> elements with <code>.form-control</code> are set to <code>width: 100%;</code> by default. Wrap labels and controls in <code>.form-group</code> for optimum spacing.</p>

    </div>


  <h2 id="forms-inline">Inline form</h2>
  <p>Add <code>.form-inline</code> to your <code>&lt;form&gt;</code> for left-aligned and inline-block controls. <strong>This only applies to forms within viewports that are at least 768px wide.</strong></p>
  <div class="bs-callout bs-callout-danger">
    <h4>Requires custom widths</h4>
    <p>Inputs, selects, and textareas are 100% wide by default in Bootstrap. To use the inline form, you'll have to set a width on the form controls used within.</p>
  </div>
  <div class="bs-callout bs-callout-warning">
    <h4>Always add labels</h4>
    <p>Screen readers will have trouble with your forms if you don't include a label for every input. For these inline forms, you can hide the labels using the <code>.sr-only</code> class.</p>

  <h2 id="forms-horizontal">Horizontal form</h2>
  <p>Use Bootstrap's predefined grid classes to align labels and groups of form controls in a horizontal layout by adding <code>.form-horizontal</code> to the form. Doing so changes <code>.form-group</code>s to behave as grid rows, so no need for <code>.row</code>.</p>

  <h2 id="forms-controls">Supported controls</h2>
  <p>Examples of standard form controls supported in an example form layout.</p>

  <div class="bs-callout bs-callout-danger">
    <h4>Type declaration required</h4>
    <p>Inputs will only be fully styled if their <code>type</code> is properly declared.</p>
  </div>
  <div class="bs-example">
    <form role="form">
      <input type="text" class="form-control" placeholder="Text input">

  </div>

  <h3>Textarea</h3>
  <p>Form control which supports multiple lines of text. Change <code>rows</code> attribute as necessary.</p>

  <h3>Checkboxes and radios</h3>
  <p>Checkboxes are for selecting one or several options in a list, while radios are for selecting one option from many.</p>
  <p>A checkbox or radio with the <code>disabled</code> attribute will be styled appropriately. To have the <code>&lt;label&gt;</code> for the checkbox or radio also display a "not-allowed" cursor when the user hovers over the label, add the <code>.disabled</code> class to your <code>.radio</code>, <code>.radio-inline</code>, <code>.checkbox</code>, <code>.checkbox-inline</code>, or <code>&lt;fieldset&gt;</code>.</p>

  <h4>Inline checkboxes and radios</h4>

  <h2 id="forms-controls-static">Static control</h2>
  <p>When you need to place plain text next to a form label within a horizontal form, use the <code>.form-control-static</code> class on a <code>&lt;p&gt;</code>.</p>
  <div class="bs-example">

  <h2 id="forms-control-focus">Input focus</h2>

  <h3 id="forms-disabled-fieldsets">Disabled fieldsets</h3>
  <p>Add the <code>disabled</code> attribute to a <code>&lt;fieldset&gt;</code> to disable all the controls within the <code>&lt;fieldset&gt;</code> at once.</p>

  <div class="bs-callout bs-callout-warning">
    <h4>Caveat about link functionality of <code>&lt;a&gt;</code></h4>
    <p>Our styles use <code>pointer-events: none</code> to try to disable the link functionality of <code>&lt;a class="btn btn-*"&gt;</code> buttons in this case, but that CSS property is not yet standardized and isn't fully supported in Opera 18 and below, or in Internet Explorer 11. So to be safe, use custom JavaScript to disable such links.</p>

  <div class="bs-callout bs-callout-danger">
    <h4>Cross-browser compatibility</h4>
    <p>While Bootstrap will apply these styles in all browsers, Internet Explorer 9 and below don't actually support the <code>disabled</code> attribute on a <code>&lt;fieldset&gt;</code>. Use custom JavaScript to disable the fieldset in these browsers.</p>

  <h2 id="forms-control-validation">Validation states</h2>
  <p>Bootstrap includes validation styles for error, warning, and success states on form controls. To use, add <code>.has-warning</code>, <code>.has-error</code>, or <code>.has-success</code> to the parent element. Any <code>.control-label</code>, <code>.form-control</code>, and <code>.help-block</code> within that element will receive the validation styles.</p>

  <h3>With optional icons</h3>
  <p>You can also add optional feedback icons with the addition of <code>.has-feedback</code> and the right icon.</p>
  <div class="bs-callout bs-callout-warning">
    <h4>Icons, labels, and input groups</h4>
    <p>Manual positioning of feedback icons is required for inputs without a label and for <a href="../components#input-groups">input groups</a> with an add-on on the right. You are strongly encouraged to provide labels for all inputs for accessibility reasons. If you wish to prevent labels from being displayed, hide them with the <code>sr-only</code> class. If you must do without labels, adjust the <code>top</code> value of the feedback icon. For input groups, adjust the <code>right</code> value to an appropriate pixel value depending on the width of your addon.</p>
