+title: Layout
+description: Give your forms some structure—from inline to horizontal to custom grid implementations—with our form layout options.
+group: forms

+
+## 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](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/form) 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`.
+
+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]({{< docsref "/utilities/spacing" >}}) are the easiest way to add some structure to forms. They provide basic grouping of labels, controls, optional form 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.
+
+{{< example >}}
+<div class="mb-3">
+  <label for="formGroupExampleInput" class="form-label">Example label</label>
+  <input type="text" class="form-control" id="formGroupExampleInput" placeholder="Example input placeholder">
+</div>
+<div class="mb-3">
+  <label for="formGroupExampleInput2" class="form-label">Another label</label>
+  <input type="text" class="form-control" id="formGroupExampleInput2" placeholder="Another input placeholder">
+</div>
+{{< /example >}}
+
+## 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 `$enable-grid-classes` Sass variable to be enabled** (on by default).
+
+{{< example >}}
+<div class="row">
+  <div class="col">
+    <input type="text" class="form-control" placeholder="First name" aria-label="First name">
+  </div>
+  <div class="col">
+    <input type="text" class="form-control" placeholder="Last name" aria-label="Last name">
+  </div>
+</div>
+{{< /example >}}
+
+## Gutters
+
+By adding [gutter modifier classes]({{< docsref "/layout/gutters" >}}), you can have control over the gutter width in as well the inline as block direction. **Also requires the `$enable-grid-classes` Sass variable to be enabled** (on by default).
+
+{{< example >}}
+<div class="row g-3">
+  <div class="col">
+    <input type="text" class="form-control" placeholder="First name" aria-label="First name">
+  </div>
+  <div class="col">
+    <input type="text" class="form-control" placeholder="Last name" aria-label="Last name">
+  </div>
+</div>
+{{< /example >}}
+
+More complex layouts can also be created with the grid system.
+
+{{< example >}}
+<form class="row g-3">
+  <div class="col-md-6">
+    <label for="inputEmail4" class="form-label">Email</label>
+    <input type="email" class="form-control" id="inputEmail4">
+  </div>
+  <div class="col-md-6">
+    <label for="inputPassword4" class="form-label">Password</label>
+    <input type="password" class="form-control" id="inputPassword4">
+  </div>
+  <div class="col-12">
+    <label for="inputAddress" class="form-label">Address</label>
+    <input type="text" class="form-control" id="inputAddress" placeholder="1234 Main St">
+  </div>
+  <div class="col-12">
+    <label for="inputAddress2" class="form-label">Address 2</label>
+    <input type="text" class="form-control" id="inputAddress2" placeholder="Apartment, studio, or floor">
+  </div>
+  <div class="col-md-6">
+    <label for="inputCity" class="form-label">City</label>
+    <input type="text" class="form-control" id="inputCity">
+  </div>
+  <div class="col-md-4">
+    <label for="inputState" class="form-label">State</label>
+    <select id="inputState" class="form-select">
+      <option selected>Choose...</option>
+      <option>...</option>
+    </select>
+  </div>
+  <div class="col-md-2">
+    <label for="inputZip" class="form-label">Zip</label>
+    <input type="text" class="form-control" id="inputZip">
+  </div>
+  <div class="col-12">
+    <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>
+  <div class="col-12">
+    <button type="submit" class="btn btn-primary">Sign in</button>
+  </div>
+</form>
+{{< /example >}}
+
+## 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.
+
+{{< example >}}
+<form>
+  <div class="row mb-3">
+    <label for="inputEmail3" class="col-sm-2 col-form-label">Email</label>
+    <div class="col-sm-10">
+      <input type="email" class="form-control" id="inputEmail3">
+    </div>
+  </div>
+  <div class="row mb-3">
+    <label for="inputPassword3" class="col-sm-2 col-form-label">Password</label>
+    <div class="col-sm-10">
+      <input type="password" class="form-control" id="inputPassword3">
+    </div>
+  </div>
+  <fieldset class="row mb-3">
+    <legend class="col-form-label col-sm-2 pt-0">Radios</legend>
+    <div class="col-sm-10">
+      <div class="form-check">
+        <input class="form-check-input" type="radio" name="gridRadios" id="gridRadios1" value="option1" checked>
+        <label class="form-check-label" for="gridRadios1">
+          First radio
+        </label>
+      </div>
+      <div class="form-check">
+        <input class="form-check-input" type="radio" name="gridRadios" id="gridRadios2" value="option2">
+        <label class="form-check-label" for="gridRadios2">
+          Second radio
+        </label>
+      </div>
+      <div class="form-check disabled">
+        <input class="form-check-input" type="radio" name="gridRadios" id="gridRadios3" value="option3" disabled>
+        <label class="form-check-label" for="gridRadios3">
+          Third disabled radio
+        </label>
+      </div>
+    </div>
+  </fieldset>
+  <div class="row mb-3">
+    <div class="col-sm-10 offset-sm-2">
+      <div class="form-check">
+        <input class="form-check-input" type="checkbox" id="gridCheck1">
+        <label class="form-check-label" for="gridCheck1">
+          Example checkbox
+        </label>
+      </div>
+    </div>
+  </div>
+  <button type="submit" class="btn btn-primary">Sign in</button>
+</form>
+{{< /example >}}
+
+### 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`.
+
+{{< example >}}
+<div class="row mb-3">
+  <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="row mb-3">
+  <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="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>
+{{< /example >}}
+
+## Column sizing
+
+As shown in the previous examples, our grid system allows you to place any number of `.col`s within a `.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 `.col`s equally split the rest, with specific column classes like `.col-sm-7`.
+
+{{< example >}}
+<div class="row g-3">
+  <div class="col-sm-7">
+    <input type="text" class="form-control" placeholder="City" aria-label="City">
+  </div>
+  <div class="col-sm">
+    <input type="text" class="form-control" placeholder="State" aria-label="State">
+  </div>
+  <div class="col-sm">
+    <input type="text" class="form-control" placeholder="Zip" aria-label="Zip">
+  </div>
+</div>
+{{< /example >}}
+
+## 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.
+
+{{< example >}}
+<form class="row gy-2 gx-3 align-items-center">
+  <div class="col-auto">
+    <label class="visually-hidden" for="autoSizingInput">Name</label>
+    <input type="text" class="form-control" id="autoSizingInput" placeholder="Jane Doe">
+  </div>
+  <div class="col-auto">
+    <label class="visually-hidden" for="autoSizingInputGroup">Username</label>
+    <div class="input-group">
+      <div class="input-group-text">@</div>
+      <input type="text" class="form-control" id="autoSizingInputGroup" placeholder="Username">
+    </div>
+  </div>
+  <div class="col-auto">
+    <label class="visually-hidden" for="autoSizingSelect">Preference</label>
+    <select class="form-select" 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">
+      <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">Submit</button>
+  </div>
+</form>
+{{< /example >}}
+
+You can then remix that once again with size-specific column classes.
+
+{{< example >}}
+<form class="row gx-3 gy-2 align-items-center">
+  <div class="col-sm-3">
+    <label class="visually-hidden" for="specificSizeInputName">Name</label>
+    <input type="text" class="form-control" id="specificSizeInputName" placeholder="Jane Doe">
+  </div>
+  <div class="col-sm-3">
+    <label class="visually-hidden" for="specificSizeInputGroupUsername">Username</label>
+    <div class="input-group">
+      <div class="input-group-text">@</div>
+      <input type="text" class="form-control" id="specificSizeInputGroupUsername" placeholder="Username">
+    </div>
+  </div>
+  <div class="col-sm-3">
+    <label class="visually-hidden" 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">
+    <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">
+    <button type="submit" class="btn btn-primary">Submit</button>
+  </div>
+</form>
+{{< /example >}}
+
+## Inline forms
+
+Use the `.row-cols-*` classes to create responsive horizontal layouts. By adding [gutter modifier classes]({{< docsref "/layout/gutters" >}}), we'll have gutters in horizontal and vertical directions. On narrow mobile viewports, the `.col-12` helps stack the form controls and more. The `.align-items-center` aligns the form elements to the middle, making the `.form-check` align properly.
+
+{{< example >}}
+<form class="row row-cols-lg-auto g-3 align-items-center">
+  <div class="col-12">
+    <label class="visually-hidden" for="inlineFormInputGroupUsername">Username</label>
+    <div class="input-group">
+      <div class="input-group-text">@</div>
+      <input type="text" class="form-control" id="inlineFormInputGroupUsername" placeholder="Username">
+    </div>
+  </div>
+
+  <div class="col-12">
+    <label class="visually-hidden" for="inlineFormSelectPref">Preference</label>
+    <select class="form-select" id="inlineFormSelectPref">
+      <option selected>Choose...</option>
+      <option value="1">One</option>
+      <option value="2">Two</option>
+      <option value="3">Three</option>
+    </select>
+  </div>
+
+  <div class="col-12">
+    <div class="form-check">
+      <input class="form-check-input" type="checkbox" id="inlineFormCheck">
+      <label class="form-check-label" for="inlineFormCheck">
+        Remember me
+      </label>
+    </div>
+  </div>
+
+  <div class="col-12">
+    <button type="submit" class="btn btn-primary">Submit</button>
+  </div>
+</form>
+{{< /example >}}
