## Always floating

Make any `.form-control` always use a floating label with visible placeholder with the `.form-floating-always` modifier class. Visible placeholders use the default input `color` and lighten to the placeholder color on focus. This matches them with other floating labels built with plaintext inputs and selects.

{{< example >}}
<div class="form-floating form-floating-always 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 form-floating-always">
<input type="password" class="form-control" id="floatingPassword" placeholder="••••••••">
<label for="floatingPassword">Password</label>
</div>
{{< /example >}}

## Layout

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