Radio button

The mutually exclusive radio buttons in their native format

The radio class is a simple wrapper around the <input type="radio"> HTML elements. It is intentionally not styled, to preserve cross-browser compatibility and the user experience.

Make sure the linked radio buttons have the same value for their name HTML attribute.

Yes No

<div class="control">
  <label class="radio">
    <input type="radio" name="answer">
    Yes
  </label>
  <label class="radio">
    <input type="radio" name="answer">
    No
  </label>
</div>

You can check a radio button by default by adding the checked HTML attribute to the <input> element.

Foo Bar

<div class="control">
  <label class="radio">
    <input type="radio" name="foobar">
    Foo
  </label>
  <label class="radio">
    <input type="radio" name="foobar" checked>
    Bar
  </label>
</div>

You can disable a radio button by adding the disabled HTML attribute to both the <label> and the <input>.

Going Not going Maybe

<div class="control">

  </label>
  <label class="radio" disabled>
    <input type="radio" name="rsvp" disabled>
    Maybe
  </label>
</div>
