Examples and usage guidelines for form control styles, layout options, and custom components for creating a wide variety of forms.
Overview
<form><div class="mb-3"><label for="exampleInputEmail1" class="form-label">Email address</label><input type="email" class="form-control" id="exampleInputEmail1" aria-describedby="emailHelp"><div id="emailHelp" class="form-text">We'll never share your email with anyone else.</div>
</div>
<div class="mb-3">
<label for="exampleInputPassword1" class="form-label">Password</label>
<input type="password" class="form-control" id="exampleInputPassword1">
</div>
<div class="mb-3 form-check">
<input type="checkbox" class="form-check-input" id="exampleCheck1">
<label class="form-check-label" for="exampleCheck1">Check me out</label>
</div>
<button type="submit" class="btn btn-primary">Submit</button>
</form>Form text
Block-level or inline-level form text can be created using .form-text.
Form text below inputs can be styled with .form-text. If a block-level element will be used, a top margin is added for easy spacing from the inputs above.
<label for="inputPassword5" class="form-label">Password</label>
<input type="password" id="inputPassword5" class="form-control" aria-describedby="passwordHelpBlock">
<div id="passwordHelpBlock" class="form-text">
Your password must be 8-20 characters long, contain letters and numbers, and must not contain spaces, special characters, or emoji.
</div>
Inline text can use any typical inline HTML element (be it a <span>, <small>, or something else) with nothing more than the .form-text class.
<div class="row g-3 align-items-center">
<div class="col-auto">
<label for="inputPassword6" class="col-form-label">Password</label>
</div>
<div class="col-auto">
<input type="password" id="inputPassword6" class="form-control" aria-describedby="passwordHelpInline">
</div>
<div class="col-auto">
<span id="passwordHelpInline" class="form-text">
Must be 8-20 characters long.
</span>
</div>
</div>Disabled forms
Add the disabled boolean attribute on an input to prevent user interactions and make it appear lighter.
<input class="form-control" id="disabledInput" type="text" placeholder="Disabled input here..." disabled>
Add the disabled attribute to a <fieldset> to disable all the controls within. Browsers treat all native form controls (<input>, <select>, and <button> elements) inside a <fieldset disabled> as disabled, preventing both keyboard and mouse interactions on them.
However, if your form also includes custom button-like elements such as <a class="btn btn-*">...</a>, these will only be given a style of pointer-events: none, meaning they are still focusable and operable using the keyboard. In this case, you must manually modify these controls by adding tabindex="-1" to prevent them from receiving focus and aria-disabled="disabled" to signal their state to assistive technologies.
