Forms

Form controls

Give textual form controls like <input>s and <textarea>s an upgrade with custom styles, sizing, focus states, and more.

Example#

Form controls are styled with custom properties (--field, --border, --focus and friends), so they adapt to color modes and to both looks.

<div class="mb-3">
  <label for="exampleFormControlInput1" class="form-label">Email address</label>
  <input type="email" class="form-control" id="exampleFormControlInput1" placeholder="name@example.com">
</div>
<div class="mb-3">
  <label for="exampleFormControlTextarea1" class="form-label">Example textarea</label>
  <textarea class="form-control" id="exampleFormControlTextarea1" rows="3"></textarea>
</div>

In the felt look, a field is a cream (or charcoal) piece pressed slightly into the felt: a soft inner shadow and the same fibre texture as the page. The focus ring is the same as in the clean look.

Sizing#

Set heights using classes like .form-control-lg and .form-control-sm.

<input class="form-control form-control-lg mb-2" type="text" placeholder=".form-control-lg" aria-label=".form-control-lg example">
<input class="form-control mb-2" type="text" placeholder="Default input" aria-label="default input example">
<input class="form-control form-control-sm" type="text" placeholder=".form-control-sm" aria-label=".form-control-sm example">

Form text#

Block-level or inline-level form text can be created using .form-text.

Form text should be explicitly associated with the form control it relates to using the aria-describedby attribute. This will ensure that assistive technologies—such as screen readers—will announce this form text when the user focuses or enters the control.

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.

Your password must be 8-20 characters long, contain letters and numbers, and must not contain spaces, special characters, or emoji. 
<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.

Must be 8-20 characters long. 
<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#

Add the disabled boolean attribute on an input to give it a grayed out appearance, remove pointer events, and prevent focusing.

<input class="form-control mb-2" type="text" placeholder="Disabled input" aria-label="Disabled input example" disabled>
<input class="form-control" type="text" value="Disabled readonly input" aria-label="Disabled input example" disabled readonly>

Readonly#

Add the readonly boolean attribute on an input to prevent modification of the input's value. readonly inputs can still be focused and selected, while disabled inputs cannot. felt-css gives them a slightly sunken background.

<input class="form-control" type="text" value="Readonly input here..." aria-label="readonly input example" readonly>

Readonly plain text#

If you want to have <input readonly> elements in your form styled as plain text, replace .form-control with .form-control-plaintext to remove the default form field styling and preserve the correct margin and padding.

<div class="mb-3 row">
  <label for="staticEmail" class="col-sm-2 col-form-label">Email</label>
  <div class="col-sm-10">
    <input type="text" readonly class="form-control-plaintext" id="staticEmail" value="email@example.com">
  </div>
</div>
<div class="mb-3 row">
  <label for="inputPassword" class="col-sm-2 col-form-label">Password</label>
  <div class="col-sm-10">
    <input type="password" class="form-control" id="inputPassword">
  </div>
</div>
<form class="row g-3">
  <div class="col-auto">
    <label for="staticEmail2" class="visually-hidden">Email</label>
    <input type="text" readonly class="form-control-plaintext" id="staticEmail2" value="email@example.com">
  </div>
  <div class="col-auto">
    <label for="inputPassword2" class="visually-hidden">Password</label>
    <input type="password" class="form-control" id="inputPassword2" placeholder="Password">
  </div>
  <div class="col-auto">
    <button type="submit" class="btn btn-primary mb-3">Confirm identity</button>
  </div>
</form>

File input#

<div class="mb-3">
  <label for="formFile" class="form-label">Default file input example</label>
  <input class="form-control" type="file" id="formFile">
</div>
<div class="mb-3">
  <label for="formFileMultiple" class="form-label">Multiple files input example</label>
  <input class="form-control" type="file" id="formFileMultiple" multiple>
</div>
<div class="mb-3">
  <label for="formFileDisabled" class="form-label">Disabled file input example</label>
  <input class="form-control" type="file" id="formFileDisabled" disabled>
</div>
<div class="mb-3">
  <label for="formFileSm" class="form-label">Small file input example</label>
  <input class="form-control form-control-sm" id="formFileSm" type="file">
</div>
<div>
  <label for="formFileLg" class="form-label">Large file input example</label>
  <input class="form-control form-control-lg" id="formFileLg" type="file">
</div>

Color#

Set the type="color" and add .form-control-color to the <input>. The modifier class sets a fixed width and height and overrides some inconsistencies between browsers.

<label for="exampleColorInput" class="form-label">Color picker</label>
<input type="color" class="form-control form-control-color" id="exampleColorInput" value="#3d64a0" title="Choose your color">

Datalists#

Datalists allow you to create a group of <option>s that can be accessed (and autocompleted) from within an <input>. These are similar to <select> elements, but come with more menu styling limitations and differences. While most browsers and operating systems include some support for <datalist> elements, their styling is inconsistent at best.

<input class="form-control" list="datalistOptions" id="exampleDataList" placeholder="Type to search...">
<datalist id="datalistOptions">
  <option value="San Francisco">
  <option value="New York">
  <option value="Seattle">
