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., `~`). + +{{< example >}} +<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> +{{< /example >}} + +When there's a `value` already defined, `<label>`s will automatically adjust to their floated position. + +{{< example >}} +<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> +{{< /example >}} + +Form validation styles also work as expected. + +{{< example >}} +<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> +{{< /example >}} + +## Textareas + +By default, `<textarea>`s with `.form-control` will be the same height as `<input>`s. + +{{< example >}} +<div class="form-floating"> + <textarea class="form-control" placeholder="Leave a comment here" id="floatingTextarea"></textarea> + <label for="floatingTextarea">Comments</label> +</div> +{{< /example >}} + +To set a custom height on your `<textarea>`, do not use the `rows` attribute.
