A form can have any number of fields. Each form field must contain a single form input, label and optionally a message.

<form class="Form" action="/" method="GET">
  <div class="Form-field">
    <label class="Form-label" for="field">Field</label>
    <input class="Form-input" type="text" id="field">
    <p class="Form-message">Hello there</p>
  </div>
</form>

Special form fields

Basic styles for more complex form fields are included in this component.

Buttons

Buttons are not styled. You are free to style buttons as you please or use an existing component like suitcss-button.

SUIT CSS Form however provides two classes:

• .Form-button – Attaches to a nested component
• .Form-wrapButton – Wraps a nested component

Both make buttons full-width and consistent with the Form styles by tweaking padding, borders and border radii only.

<form class="Form" action="/" method="GET">
  <div class="Form-field">
    <label class="Form-label" for="field">Field</label>
    <input class="Form-input" type="text" id="field">
  </div>
  <div class="Form-field">
    <!-- .Form-button attaches to the .Button component -->
    <button class="Form-button Button">
      Submit
    </button>
  </div>
  <div class="Form-field u-inlineBlock">
    <!-- .Form-wrapButton wraps the .Button component -->
    <span class="Form-wrapButton">
      <button class="Button">Submit</button>
    </span>

  </div>
</form>

Tip: Use an utility class e.g. u-inlineBlock when you don't want full-width buttons.

Checkbox and Radio inputs

• Form-field--checkbox
• Form-field--radio

Checkbox and radio inputs are Form-field modifiers. Use one Form-field per Form-input.

<form class="Form" action="/" method="GET">
  <div class="Form-field Form-field--checkbox">
    <input class="Form-input" type="checkbox" id="check-field">
    <label class="Form-label" for="check-field">Field</label>
  </div>
  <label class="Form-field Form-field--radio">
    <input class="Form-input" type="radio">
    <span class="Form-label">Field</span>
  </label>
</form>

Custom Select

Modern browsers that support the CSS3 appearance property get basic custom select styles without any additional class needed:

• Padding, border and border radii match other inputs styles.
• Custom arrow.

Horizontal forms

Use a layout component like suitcss-grid.

Vertical spacing between Form-field

Form--spaced adds uniform vertical space between Form-field.

<form class="Form Form--spaced" action="/" method="GET">
  <div class="Form-field">
    <label class="Form-label" for="field-regular">Field</label>
    <input class="Form-input" type="text" id="field-regular">
  </div>
  <div class="Form-field Form-field--radio">
    <input class="Form-input" type="radio" id="radio-field">
    <label class="Form-label" for="radio-field">Field</label>
  </div>
  <div class="Form-field Form-field--radio">
    <input class="Form-input" type="radio" id="radio-field1">
    <label class="Form-label" for="radio-field1">Field</label>
  </div>
</form>

N.B. Checkboxes or radio inputs are grouped and the space between each is half of the regular Form-field margin.
