Form

Elements

Related elements (radio buttons and checkboxes in this example) should have a role="radiogroup" / role="group" applied to its container to indicate group membership of the contained elements.

The aria-labelledby is used to reference the ID of the text that labels the group.

Horizontal

To create a horizontal form (horizontally align labels with input), apply modifier .env-form--horizontal to the form wrapper. The label of the element takes up 20% of the width and the .env-form-element__control uses the remaining width.

<div class="env-form env-form--horizontal">
   <div class="env-form-element">
      <label for="first-name" class="env-form-element__label">First name</label>
      <div class="env-form-element__control">
         <input type="text" class="env-form-input" id="first-name" />
      </div>
   </div>
   <div class="env-form-element">
      <label for="last-name" class="env-form-element__label">Last name</label>
      <div class="env-form-element__control">
         <input type="text" class="env-form-input" id="last-name" />
      </div>
   </div>
   <div class="env-form-element">
      <span class="env-form-element__label" id="subjects-header">Subjects</span>
      <div
         class="env-form-element__control"
         role="group"
         aria-labelledby="subjects-header"
      >
         <div class="env-checkbox">
            <input type="checkbox" name="options" id="cb4" />
            <label class="env-form-element__label" for="cb4">
               <span class="env-checkbox__fake"></span>
               <span class="env-checkbox__label">Subject</span>
            </label>
         </div>
         <div class="env-checkbox">
            <input type="checkbox" name="options" id="cb5" />
            <label class="env-form-element__label" for="cb5">
               <span class="env-checkbox__fake"></span>
               <span class="env-checkbox__label">Subject 2</span>
            </label>
         </div>
         <div class="env-checkbox">
            <input type="checkbox" name="options" id="cb6" />
            <label class="env-form-element__label" for="cb6">
               <span class="env-checkbox__fake"></span>
               <span class="env-checkbox__label">Subject 3</span>
            </label>
         </div>
      </div>
   </div>
   <div class="env-form-element">
      <button type="submit" class="env-button env-button--primary">
         Submit
      </button>
   </div>
</div>

Inline

Apply modifier .env-form--inline to the form wrapper to display elements inline.

<div class="env-form env-form--inline">
   <div class="env-form-element">
      <label for="country" class="env-form-element__label">Country</label>
      <div class="env-form-element__control">
         <input type="text" class="env-form-input" id="country" />
      </div>
   </div>
   <div class="env-form-element">
      <label for="city" class="env-form-element__label">City</label>
      <div class="env-form-element__control">
         <input type="text" class="env-form-input" id="city" />
      </div>
   </div>
   <div class="env-form-element">
      <div class="env-form-element__control">
         <div class="env-checkbox">
            <input type="checkbox" name="options" id="cb7" />
            <label class="env-form-element__label" for="cb7">
               <span class="env-checkbox__fake"></span>
               <span class="env-checkbox__label">Remember me</span>
            </label>
         </div>
      </div>
   </div>
   <div class="env-form-element">
      <button type="submit" class="env-button env-button--primary">
         Submit
      </button>
   </div>
</div>

Hybrid

To position multiple elements on a row, wrap target elements (.env-form-element) with a .env-form__row container. Use modifer .env-form-element--* to specify the length of an element, relative to other elements on the row. Valid values 1-6. Default is 1

<div class="env-form">
   <div class="env-form__row">
      <div class="env-form-element">
         <label for="username" class="env-form-element__label">Username</label>
         <div class="env-form-element__control">
            <input type="text" class="env-form-input" id="username" />
         </div>
      </div>
      <div class="env-form-element">
         <label for="full-name" class="env-form-element__label"
            >Full name</label
         >
         <div class="env-form-element__control">
            <input type="text" class="env-form-input" id="full-name" />
         </div>
      </div>
   </div>
   <div class="env-form__row">
      <div class="env-form-element env-form-element--2">
         <label for="address" class="env-form-element__label">Address</label>
         <div class="env-form-element__control">
            <input type="text" class="env-form-input" id="address" />
         </div>
      </div>
      <div class="env-form-element">
         <label for="contact-tel" class="env-form-element__label"
            >Telephone</label
         >
         <div class="env-form-element__control">
            <input type="tel" class="env-form-input" id="contact-tel" />
         </div>
      </div>
   </div>
   <div class="env-form-element">
      <label for="other" class="env-form-element__label">Other</label>
      <div class="env-form-element__control">
         <input type="text" class="env-form-input" id="other" />
      </div>
   </div>
   <div class="env-form-element">
      <button type="submit" class="env-button env-button--primary">
         Submit
      </button>
   </div>
</div>

Help text

Use .env-form-element__help for help texts associated with a form element. The aria-describedby attribute should be used to reference the ID of the text that describes the element.

<div class="env-form">
   <div class="env-form-element">
      <label for="password" class="env-form-element__label">Password</label>
      <div class="env-form-element__control">
         <input
            type="password"
            class="env-form-input"
            id="password"
            aria-describedby="password-help"
         />
      </div>
      <span id="password-help" class="env-form-element__help"
         >Enter a secure password</span
      >
   </div>
</div>

States

Elements with the disabled attribute recieve a not-allowed cursor while readonly elements maintain the default cursor. For disabled radio buttons and checkboxes, apply modifier .env-form-radio--disabled / .env-checkbox--disabled to its wrapper for a lighter label and a not-allowed cursor.

<div class="env-form">
   <div class="env-form-element">
      <label for="disabled" class="env-form-element__label"
         >Disabled text input</label
      >
      <div class="env-form-element__control">
         <input
            type="text"
            class="env-form-input"
            id="disabled"
            placeholder="Disabled"
            disabled
         />
      </div>
   </div>
   <div class="env-form-element">
      <label for="disabled-select" class="env-form-element__label"
         >Disabled select</label
      >
      <div class="env-form-element__control">
         <select class="env-form-input" id="disabled-select" disabled>
            <option>Disabled</option>
         </select>
      </div>
   </div>
   <div class="env-form-element">
      <div class="env-form-element__control">
         <div class="env-checkbox env-checkbox--disabled">
            <input type="checkbox" name="options" id="cb8" disabled />
            <label class="env-form-element__label" for="cb8">
               <span class="env-checkbox__fake"></span>
               <span class="env-checkbox__label">Disabled checkbox</span>
            </label>
         </div>
      </div>
   </div>
   <div class="env-form-element">
      <div class="env-form-element__control">
         <div class="env-form-radio env-form-radio--disabled">
            <label class="env-form-element__label">

               Disabled radio button
            </label>

      </div>
   </div>
   <div class="env-form-element">
      <label for="readonly" class="env-form-element__label"
         >Readonly text input</label
      >
      <div class="env-form-element__control">
         <input
            type="text"
            class="env-form-input"
            id="readonly"
            placeholder="Readonly"
            readonly
         />
      </div>
   </div>
</div>

Validation

Add modifiers .env-form-element--success, .env-form-element--warning or .env-form-element--danger to define a validation state. The aria-describedby attribute should be used to reference the ID of the text that describes the element.

<div class="env-form">
   <div class="env-form-element env-form-element--success">
      <label for="success" class="env-form-element__label">Success</label>
      <div class="env-form-element__control">

            aria-describedby="success-feedback"
         />
      </div>
      <span id="success-feedback" class="env-form-element__feedback"
