Switch

Now you can tell your users to flip the switch or switch off.


Basics

Add the .switch class to an element to create a switch. Inside the switch, add an <input type="checkbox"> with the class .switch-input. Next to that, create a <label> with the class .switch-paddle.

Give the <input> a unique ID and point the <label> to it with the for attribute. This makes the switch clickable.

Inside the switch label is screen reader-only text, which uses the .show-for-sr class to visually mask the text.

Make sure the HTML of the switch goes in the order you see above—<input>, then <label>

<div class="switch">
  <input class="switch-input" id="exampleSwitch" type="checkbox" name="exampleSwitch">
  <label class="switch-paddle" for="exampleSwitch">
    <span class="show-for-sr">Download Kittens</span>
  </label>
</div>

Radio Switch

You can also use <input type="radio"> instead of checkbox to create a series of options.

<div class="switch">
  <input class="switch-input" id="exampleRadioSwitch1" type="radio" checked name="testGroup">
  <label class="switch-paddle" for="exampleRadioSwitch1">
    <span class="show-for-sr">Bulbasaur</span>
  </label>
</div>

Sizing Classes

Use the classes .tiny, .small, or .large to change the switch size.

<div class="switch tiny">
  <input class="switch-input" id="tinySwitch" type="checkbox" name="exampleSwitch">
  <label class="switch-paddle" for="tinySwitch">
    <span class="show-for-sr">Tiny Sandwiches Enabled</span>
  </label>
</div>

<div class="switch small">
  <input class="switch-input" id="smallSwitch" type="checkbox" name="exampleSwitch">
  <label class="switch-paddle" for="smallSwitch">
    <span class="show-for-sr">Small Portions Only</span>
  </label>
</div> 

<div class="switch large">
  <input class="switch-input" id="largeSwitch" type="checkbox" name="exampleSwitch">
  <label class="switch-paddle" for="largeSwitch">
    <span class="show-for-sr">Show Large Elephants</span>
  </label>
</div>

Inner Labels

You can place active and inactive text inside of a switch. The active text (.switch-active) only displays when the switch is on, and the inactive text (.switch-inactive) only displays when the switch is off.

Active/inactive text goes inside of the switch's <label>.

Depending on the length of the words you place inside the switch, you may need to fine-tune the left or right CSS properties of the text to get it positioned right.

Add aria-hidden="true" to these labels to prevent AT from reading them.

    <span class="switch-active" aria-hidden="true">Yes</span>
    <span class="switch-inactive" aria-hidden="true">No</span>
  </label>
</div>
