title: Add class to each link when it has focus (jQuery)
body: <p>I have the code below. The problem is the class is added to all links on the page and not the one in focus.</p>
  
  <pre><code>$('a.going__outside').on('focusin', function(){
          $('a.going__outside').each(function(){
              $('a.going__outside span').removeClass('sr-only');
              }).on('focusout', function(){
                  $('a.going__outside span').addClass('sr-only');
              });
          });
  </code></pre>
