                <h2>Toggle Switch</h2>
<p id="version">Last updated in <a href="" target="blank">rc 1.1.7</a></p>
<p>Toggle switches may be in one of two positions, usually on or off. Behind the scenes they are marked up as checkboxes.</p>
<p>The HTML structure consists of a container <code>label</code> element with an <code>input</code> followed by a corresponding element with the accessible name and an optional element with text for the state, e.g. ON/OFF. If using the state, you will need to write a script for the onchange event.</p>
<label class="switch-toggle" for="toggle">
  <input type="checkbox" id="toggle">
  <div class="togglelabel">Label for toggle</div>
  <div class="toggletext">off</div>

<h3>Previous Implementation</h3>
<p>As with the implementation above, our original implementation uses the label to create the visual switch. However, we would add a second label to associate an accessible name with the checkbox. According to this actually <em>created</em> an accessibility issue, and Lighthouse will flag it as a problem: </p>
<blockquote>If you unintentionally associate multiple labels with a single control, you'll create inconsistent behavior across browsers and assistive technologies: some will read the first label, some will read the last label, and others will read both labels.</blockquote>
<div class="toggle-switch">
  <input type="checkbox" id="oldtoggle">
  <label class="switchtoggle" for="oldtoggle" data-checked="ON"></label>
  <label for="oldtoggle">We shouldn't do this</label>
