Layout

Give your forms some structure—from inline to horizontal to custom grid implementations—with our form layout options.

Forms

Every group of form fields should reside in a <form> element. Bootstrap provides no default styling for the <form> element, but there are some powerful browser features that are provided by default.

  • New to browser forms? Consider reviewing the MDN form docs for an overview and complete list of available attributes.
  • <button>s within a <form> default to type="submit", so strive to be specific and always include a type.
  • You can disable every form element within a form with the disabled attribute on the <form>.

Since Bootstrap applies display: block and width: 100% 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.

Utilities

Margin utilities are the easiest way to add some structure to forms. They provide basic grouping of labels, controls, optional help text, and form validation messaging. We recommend sticking to margin-bottom utilities, and using a single direction throughout the form for consistency.

Feel free to build your forms however you like, with <fieldset>s, <div>s, or nearly any other element.

<form>
  <div class="mb-3">
    <label for="formGroupExampleInput">Example label</label>
    <input type="text" class="form-control" id="formGroupExampleInput" placeholder="Example input placeholder">
  </div>
  <div class="mb-3">
    <label for="formGroupExampleInput2">Another label</label>
    <input type="text" class="form-control" id="formGroupExampleInput2" placeholder="Another input placeholder">
  </div>
</form>

Form grid

More complex forms can be built using our grid classes. Use these for form layouts that require multiple columns, varied widths, and additional alignment options. Requires the $enable-grid-classes Sass variable to be enabled (on by default).

<form>
  <div class="row">
    <div class="col">
      <input type="text" class="form-control" placeholder="First name">
    </div>
    <div class="col">
      <input type="text" class="form-control" placeholder="Last name">
    </div>
  </div>
</form>

Form row

You may also swap .row for .form-row, a variation of our standard grid row that overrides the default column gutters for tighter and more compact layouts. Also requires the $enable-grid-classes Sass variable to be enabled (on by default).

<form>
  <div class="form-row">
    <div class="col">
      <input type="text" class="form-control" placeholder="First name">
    </div>
    <div class="col">
      <input type="text" class="form-control" placeholder="Last name">
    </div>
  </div>
</form>

More complex layouts can also be created with the grid system.

<form>
  <div class="form-row">
    <div class="mb-3 col-md-6">
      <label for="inputEmail4">Email</label>
      <input type="email" class="form-control" id="inputEmail4">
    </div>
    <div class="mb-3 col-md-6">
      <label for="inputPassword4">Password</label>
      <input type="password" class="form-control" id="inputPassword4">
    </div>
  </div>
  <div class="mb-3">
    <label for="inputAddress">Address</label>
    <input type="text" class="form-control" id="inputAddress" placeholder="1234 Main St">
  </div>
  <div class="mb-3">
    <label for="inputAddress2">Address 2</label>
    <input type="text" class="form-control" id="inputAddress2" placeholder="Apartment, studio, or floor">
  </div>
  <div class="form-row">
    <div class="mb-3 col-md-6">
      <label for="inputCity">City</label>
      <input type="text" class="form-control" id="inputCity">
    </div>
    <div class="mb-3 col-md-4">
      <label for="inputState">State</label>
      <select id="inputState" class="form-select">
        <option selected>Choose...</option>
        <option>...</option>
      </select>
    </div>
    <div class="mb-3 col-md-2">
      <label for="inputZip">Zip</label>
      <input type="text" class="form-control" id="inputZip">
    </div>
  </div>
  <div class="mb-3">
    <div class="form-check">
      <input class="form-check-input" type="checkbox" id="gridCheck">
      <label class="form-check-label" for="gridCheck">
        Check me out
      </label>
    </div>
  </div>
  <button type="submit" class="btn btn-primary">Sign in</button>
</form>

Horizontal form

Create horizontal forms with the grid by adding the .row class to form groups and using the .col-*-* classes to specify the width of your labels and controls. Be sure to add .col-form-label to your <label>s as well so they're vertically centered with their associated form controls.

At times, you maybe need to use margin or padding utilities to create that perfect alignment you need. For example, we've removed the padding-top on our stacked radio inputs label to better align the text baseline.

<form>
  <div class="mb-3 row">
    <label for="inputEmail3" class="col-sm-2 col-form-label">Email</label>

            Third disabled radio

    </div>
  </div>
</form>

Horizontal form label sizing

Be sure to use .col-form-label-sm or .col-form-label-lg to your <label>s or <legend>s to correctly follow the size of .form-control-lg and .form-control-sm.

<form>
  <div class="mb-3 row">
    <label for="colFormLabelSm" class="col-sm-2 col-form-label col-form-label-sm">Email</label>
    <div class="col-sm-10">
      <input type="email" class="form-control form-control-sm" id="colFormLabelSm" placeholder="col-form-label-sm">
    </div>
  </div>
  <div class="mb-3 row">
    <label for="colFormLabel" class="col-sm-2 col-form-label">Email</label>
    <div class="col-sm-10">
      <input type="email" class="form-control" id="colFormLabel" placeholder="col-form-label">
    </div>
  </div>
  <div class="mb-3 row">
    <label for="colFormLabelLg" class="col-sm-2 col-form-label col-form-label-lg">Email</label>
    <div class="col-sm-10">
      <input type="email" class="form-control form-control-lg" id="colFormLabelLg" placeholder="col-form-label-lg">
    </div>
  </div>
</form>

Column sizing

As shown in the previous examples, our grid system allows you to place any number of .cols within a .row or .form-row. They'll split the available width equally between them. You may also pick a subset of your columns to take up more or less space, while the remaining .cols equally split the rest, with specific column classes like .col-7.

<form>
  <div class="form-row">
    <div class="col-7">
      <input type="text" class="form-control" placeholder="City">
    </div>
    <div class="col">
      <input type="text" class="form-control" placeholder="State">
    </div>
    <div class="col">
      <input type="text" class="form-control" placeholder="Zip">
    </div>
  </div>
</form>

Auto-sizing

The example below uses a flexbox utility to vertically center the contents and changes .col to .col-auto so that your columns only take up as much space as needed. Put another way, the column sizes itself based on the contents.

@
<form>
  <div class="form-row align-items-center">
    <div class="col-auto">
      <label class="sr-only" for="autoSizingInput">Name</label>
      <input type="text" class="form-control mb-2" id="autoSizingInput" placeholder="Jane Doe">
    </div>
    <div class="col-auto">
      <label class="sr-only" for="autoSizingInputGroup">Username</label>
      <div class="input-group mb-2">
        <div class="input-group-prepend">
          <div class="input-group-text">@</div>
        </div>
        <input type="text" class="form-control" id="autoSizingInputGroup" placeholder="Username">
      </div>
    </div>
    <div class="col-auto">
      <label class="sr-only" for="autoSizingSelect">Preference</label>
      <select class="form-select mb-2" id="autoSizingSelect">
        <option selected>Choose...</option>
        <option value="1">One</option>
        <option value="2">Two</option>
        <option value="3">Three</option>
      </select>
    </div>
    <div class="col-auto">
      <div class="form-check mb-2">
        <input class="form-check-input" type="checkbox" id="autoSizingCheck">
        <label class="form-check-label" for="autoSizingCheck">
          Remember me
        </label>
      </div>
    </div>
    <div class="col-auto">
      <button type="submit" class="btn btn-primary mb-2">Submit</button>
    </div>
  </div>
</form>

You can then remix that once again with size-specific column classes.

@
<form>
  <div class="form-row align-items-center">
    <div class="col-sm-3 my-1">
      <label class="sr-only" for="specificSizeInputName">Name</label>
      <input type="text" class="form-control" id="specificSizeInputName" placeholder="Jane Doe">
    </div>
    <div class="col-sm-3 my-1">
      <label class="sr-only" for="specificSizeInputGroupUsername">Username</label>
      <div class="input-group">
        <div class="input-group-prepend">
          <div class="input-group-text">@</div>
        </div>
        <input type="text" class="form-control" id="specificSizeInputGroupUsername" placeholder="Username">
      </div>
    </div>
    <div class="col-sm-3 my-1">
      <label class="sr-only" for="specificSizeSelect">Preference</label>
      <select class="form-select" id="specificSizeSelect">
        <option selected>Choose...</option>
        <option value="1">One</option>
        <option value="2">Two</option>
        <option value="3">Three</option>
      </select>
    </div>
    <div class="col-auto my-1">
      <div class="form-check">
        <input class="form-check-input" type="checkbox" id="autoSizingCheck2">
        <label class="form-check-label" for="autoSizingCheck2">
          Remember me
        </label>
      </div>
    </div>
    <div class="col-auto my-1">
      <button type="submit" class="btn btn-primary">Submit</button>
    </div>
  </div>
</form>

Inline forms

Use the .form-inline class to display a series of labels, form controls, and buttons on a single horizontal row. Form controls within inline forms vary slightly from their default states.

  • Controls are display: flex, collapsing any HTML white space and allowing you to provide alignment control with spacing and flexbox utilities.
  • Controls and input groups receive width: auto to override the Bootstrap default width: 100%.
  • Controls only appear inline in viewports that are at least 576px wide to account for narrow viewports on mobile devices.

You may need to manually address the width and alignment of individual form controls with spacing utilities (as shown below). Lastly, be sure to always include a <label> with each form control, even if you need to hide it from non-screenreader visitors with .sr-only.

@
<form class="form-inline">
  <label class="sr-only" for="inlineFormInputName">Name</label>
  <input type="text" class="form-control mb-2 mr-sm-2" id="inlineFormInputName" placeholder="Jane Doe">

  <label class="sr-only" for="inlineFormInputGroupUsername">Username</label>
  <div class="input-group mb-2 mr-sm-2">
    <div class="input-group-prepend">
      <div class="input-group-text">@</div>
    </div>
    <input type="text" class="form-control" id="inlineFormInputGroupUsername" placeholder="Username">
  </div>

  <label class="sr-only" for="inlineFormSelectPref">Preference</label>
  <select class="form-select mb-2 mr-sm-2" id="inlineFormSelectPref">
    <option selected>Choose...</option>
    <option value="1">One</option>
    <option value="2">Two</option>
    <option value="3">Three</option>
  </select>

  <div class="form-check mb-2 mr-sm-2">
    <input class="form-check-input" type="checkbox" id="inlineFormCheck">
    <label class="form-check-label" for="inlineFormCheck">
      Remember me
    </label>
  </div>

  <button type="submit" class="btn btn-primary mb-2">Submit</button>
</form>

Alternatives to hidden labels

Assistive technologies such as 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 .sr-only class. There are further alternative methods of providing a label for assistive technologies, such as the aria-label, aria-labelledby or title attribute. If none of these are present, assistive technologies may resort to using the placeholder attribute, if present, but note that use of placeholder as a replacement for other labeling methods is not advised.
