Layout

Utilities

Margin utilities 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.

<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>

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.

<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>

Gutters

By adding gutter modifier classes, you can have control over the gutter width in as well the inline as block direction.

<div class="row g-3">
    <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>

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

<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>

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="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-sm-2 col-form-label 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>

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.

<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>

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 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>

Inline forms

Use the .col-auto class to create horizontal layouts. By adding gutter modifier classes, we’ll have gutters in horizontal and vertical directions. The .align-items-center aligns the form elements to the middle, making the .form-checkbox align properly.

<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>
