<h2 id="accessibility">Accessibility</h2>
<p>Screen readers will have trouble with your forms if you don’t include a label for every input. For these input groups, ensure that any additional label or functionality is conveyed to assistive technologies.</p>
<p>The exact technique to be used (<code class="highlighter-rouge"><label></code> elements hidden using the <code class="highlighter-rouge">.sr-only</code> class, or use of the <code class="highlighter-rouge">aria-label</code> and <code class="highlighter-rouge">aria-labelledby</code> attributes, possibly in combination with <code class="highlighter-rouge">aria-describedby</code>) and what additional information will need to be conveyed will vary depending on the exact type of interface widget you’re implementing. The examples in this section provide a few suggested, case-specific approaches.</p>
