Floating labels

Create beautifully simple form labels that float over your input fields.

On this page

Example

Wrap a pair of <input class="form-control"> and <label> elements in .form-floating to enable floating labels with Bootstrap’s textual form fields. A placeholder is required on each <input> as our method of CSS-only floating labels uses the :placeholder-shown pseudo-element. Also note that the <input> must come first so we can utilize a sibling selector (e.g., ~).

html 
<div class="form-floating mb-3">
 <input type="email" class="form-control" id="floatingInput" placeholder="name@example.com">
 <label for="floatingInput">Email address</label>
</div>
<div class="form-floating">
 <input type="password" class="form-control" id="floatingPassword" placeholder="Password">
 <label for="floatingPassword">Password</label>
</div>

When there’s a value already defined, <label>s will automatically adjust to their floated position.

html 
<form class="form-floating">
 <input type="email" class="form-control" id="floatingInputValue" placeholder="name@example.com" value="test@example.com">
 <label for="floatingInputValue">Input with value</label>
</form>

Form validation styles also work as expected.

html 
<form class="form-floating">
 <input type="email" class="form-control is-invalid" id="floatingInputInvalid" placeholder="name@example.com" value="test@example.com">
 <label for="floatingInputInvalid">Invalid input</label>
</form>

Textareas

By default, <textarea>s with .form-control will be the same height as <input>s.

html 
<div class="form-floating">
 <textarea class="form-control" placeholder="Leave a comment here" id="floatingTextarea"></textarea>
 <label for="floatingTextarea">Comments</label>
</div>

To set a custom height on your <textarea>, do not use the rows attribute. Instead, set an explicit height (either inline or via custom CSS).

html 
<div class="form-floating">
 <textarea class="form-control" placeholder="Leave a comment here" id="floatingTextarea2" style="height: 100px"></textarea>
 <label for="floatingTextarea2">Comments</label>
</div>

Selects

Other than .form-control, floating labels are only available on .form-selects. They work in the same way, but unlike <input>s, they’ll always show the <label> in its floated state. Selects with size and multiple are not supported.

html 
<div class="form-floating">
 <select class="form-select" id="floatingSelect" aria-label="Floating label select example">
 <option selected>Open this select menu</option>
 <option value="1">One</option>
 <option value="2">Two</option>
 <option value="3">Three</option>
 </select>
 <label for="floatingSelect">Works with selects</label>
</div>

Readonly plaintext

Floating labels also support .form-control-plaintext, which can be helpful for toggling from an editable <input> to a plaintext value without affecting the page layout.

html 
<div class="form-floating mb-3">
 <input type="email" readonly class="form-control-plaintext" id="floatingEmptyPlaintextInput" placeholder="name@example.com">
 <label for="floatingEmptyPlaintextInput">Empty input</label>
</div>
<div class="form-floating mb-3">
 <input type="email" readonly class="form-control-plaintext" id="floatingPlaintextInput" placeholder="name@example.com" value="name@example.com">
 <label for="floatingPlaintextInput">Input with value</label>
</div>

Input groups

Floating labels also support .input-group.

@
html 
<div class="input-group mb-3">
 <span class="input-group-text">@</span>
 <div class="form-floating">
 <input type="text" class="form-control" id="floatingInputGroup1" placeholder="Username">
 <label for="floatingInputGroup1">Username</label>
 </div>
</div>

When using .input-group and .form-floating along with form validation, the -feedback should be placed outside of the .form-floating, but inside of the .input-group. This means that the feedback will need to be shown using javascript.

@
Please choose a username.
html 
<div class="input-group has-validation">
 <span class="input-group-text">@</span>
 <div class="form-floating is-invalid">
 <input type="text" class="form-control is-invalid" id="floatingInputGroup2" placeholder="Username" required>
 <label for="floatingInputGroup2">Username</label>
 </div>
 <div class="invalid-feedback">
 Please choose a username.
 </div>
</div>

Layout

When working with the Bootstrap grid system, be sure to place form elements within column classes.

html 
<div class="row g-2">
 <div class="col-md">
 <div class="form-floating">
 <input type="email" class="form-control" id="floatingInputGrid" placeholder="name@example.com" value="mdo@example.com">
 <label for="floatingInputGrid">Email address</label>
 </div>
 </div>
 <div class="col-md">
 <div class="form-floating">
 <select class="form-select" id="floatingSelectGrid">
 <option selected>Open this select menu</option>
 <option value="1">One</option>
 <option value="2">Two</option>
 <option value="3">Three</option>
 </select>
 <label for="floatingSelectGrid">Works with selects</label>
 </div>
 </div>
</div>
